00:04:53,910 اللي صار زيادة الانفاق زود ال aggregate 69 00:04:53,910 --> 00:04:57,450 expenditure وبتالي there is upward shifting of the 70 00:04:57,450 --> 00:05:00,610 aggregate expenditure function صح؟ صار في عندي هي 71 00:05:00,610 --> 00:05:03,570 ال aggregate expenditure function there is an 72 00:05:03,570 --> 00:05:06,490 upward shifting of the aggregate expenditure to 73 00:05:06,490 --> 00:05:11,750 aggregate expenditure 2 equals C plus I plus G2 74 00:05:11,750 --> 00:05:17,440 مظبوط؟ right؟شو صار في الناتج في ال aggregate 75 00:05:17,440 --> 00:05:25,600 output؟ this is E to exactly to Y2 so there is an 76 00:05:25,600 --> 00:05:30,140 increasing in the aggregate output from Y1 to Y2 77 00:05:30,140 --> 00:05:34,920 right صح ولا لأ؟ الزيادة في الناتج leads to 78 00:05:34,920 --> 00:05:38,580 increasing to aggregate income مظبوط؟ so let's 79 00:05:38,580 --> 00:05:41,840 follow or complete the analysis here increasing of 80 00:05:41,840 --> 00:05:44,900 Y means increasing of aggregate income 81 00:05:49,360 --> 00:05:53,360 Increasing in income شو بيعمل في ال money demand؟ 82 00:06:02,020 --> 00:06:06,380 لذلك نحن لدينا تغيير كلمة صحيح للطريقة التي تتطلب 83 00:06:06,380 --> 00:06:10,400 المال إذا كنا نتكلم عن ماركت المال ، فهناك تغيير 84 00:06:10,400 --> 00:06:15,460 كلمة صحيح للطريقة التي تتطلب المال ، صح؟ إذا لو 85 00:06:15,460 --> 00:06:19,000 بدأ أجي لـ money demand curve أو ماركت المال ، 86 00:06:19,000 --> 00:06:24,720 نستطيع أن نرى ما 87 00:06:24,720 --> 00:06:30,010 هوالعامة المالية في العامة المالية لدينا مصادر 88 00:06:30,010 --> 00:06:31,670 المال والمصادر المالية دماغ دماغ دماغ دماغ دماغ 89 00:06:31,670 --> 00:06:35,990 دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ 90 00:06:35,990 --> 00:06:39,370 دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ 91 00:06:39,370 --> 00:06:42,990 دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ 92 00:06:42,990 --> 00:06:45,690 دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ دماغ 93 00:06:45,690 --> 00:06:52,730 دماغ دماغ دماغ 94 00:06:52,730 --> 00:07:02,370 دEQM1 So this is QM and this is R And this is E1 95 00:07:02,370 --> 00:07:08,210 Now the increasing in money demand leads to what? 96 00:07:08,610 --> 00:07:11,950 A rightward shifting exactly in the money demand 97 00:07:11,950 --> 00:07:14,690 curve وبالتالي هى فى عندي صار فى انتقال فى ال 98 00:07:14,690 --> 00:07:18,530 money demand curve لوين؟ لليمين to money demand 2 99 00:07:20,870 --> 00:07:26,110 صح ولا لأ؟ اذا .. so we have a new interest rate 100 00:07:26,110 --> 00:07:34,070 this is R2 increased مظبوط؟ طيب so the .. let's .. 101 00:07:34,070 --> 00:07:39,210 so this is A2 so let's come back to our analysis 102 00:07:39,210 --> 00:07:42,250 here as you see the increasing in money demand 103 00:07:42,250 --> 00:07:46,890 leads to what? increasing in the interest rate طب 104 00:07:46,890 --> 00:07:49,950 الزيادة في سعر الفائدة شو بتعمل في ال investment؟ 105 00:07:50,270 --> 00:07:53,850 بتنزلوا there is an inverse relationship بين ال 106 00:07:53,850 --> 00:07:56,630 interest rate و ال investment هيوة لو بده أرجع 107 00:07:56,630 --> 00:08:00,170 لرسمها لجهة so the increasing and the interest 108 00:08:00,170 --> 00:08:05,850 rate leads to a decreasing in I or the planned 109 00:08:05,850 --> 00:08:12,650 investment مظبوط ولا لأ؟ لأنه أصلا خليني أنغطي هذا 110 00:08:12,650 --> 00:08:17,090 هيك بس بيسكت 111 00:08:18,600 --> 00:08:24,320 Okay رجع لك كمان شوية okay so the increasing in 112 00:08:24,320 --> 00:08:27,780 the interest rate leads to a decreasing in the 113 00:08:27,780 --> 00:08:30,280 planned investment مظبوط ولا لأ طب ال planned 114 00:08:30,280 --> 00:08:33,560 investment is part of aggregate expenditure صح 115 00:08:33,560 --> 00:08:38,820 exactly so we have a decreasing in aggregate 116 00:08:38,820 --> 00:08:44,580 expenditure مظبوط exactly yes with a smaller than 117 00:08:44,580 --> 00:08:49,390 the previousفيز طبعا هذا ايه اكي صار في and with a 118 00:08:49,390 --> 00:08:53,050 small مصبوح 119 00:08:53,050 --> 00:08:58,510 اذا شو اللي صار هل هيرجع ال aggregate expenditure 120 00:08:58,510 --> 00:09:05,930 شو يصير هيرجع ينزل مرة تانية بس بالنسبة بسيطة so 121 00:09:05,930 --> 00:09:11,190 here we have a downward shifting in the aggregate 122 00:09:11,190 --> 00:09:11,990 expenditure 123 00:09:14,850 --> 00:09:19,470 صح هيو جينا ليش ل aggregate expenditure three C 124 00:09:19,470 --> 00:09:27,410 plus I plus G two plus I two اللي نزلها so this is 125 00:09:27,410 --> 00:09:33,730 I two sorry this is I two so in the first case شو 126 00:09:33,730 --> 00:09:39,370 كان الوضع كان في عندي upward shifting and then we 127 00:09:39,370 --> 00:09:45,400 have a downward shifting with a small amountصح قال 128 00:09:45,400 --> 00:09:53,740 لها this leads to what the final this is a3 شو 129 00:09:53,740 --> 00:09:58,280 يعمل في النتيجة exactly so we have a small 130 00:09:58,280 --> 00:10:02,400 decreasing in the aggregate output اذا هنا we have 131 00:10:02,400 --> 00:10:05,300 a small decreasing in the aggregate expenditure 132 00:10:05,300 --> 00:10:12,860 leads to a smaller decreasing in y صح حيومثبت ولا 133 00:10:12,860 --> 00:10:19,800 لأ؟ صح؟ شوفوا هذا ال small decreasing اذا كانت 134 00:10:19,800 --> 00:10:24,860 الدولة او ال government مخطط انه يزيد الناتج from 135 00:10:24,860 --> 00:10:30,700 Y1 to Y2 يعني سببز انه بدي يزيد الناتج من 100 136 00:10:30,700 --> 00:10:36,460 مليون ل 300 مليون unfortunately as a result of or 137 00:10:36,460 --> 00:10:42,560 due to the crowding out صار في عنديdeduction or 138 00:10:42,560 --> 00:10:47,740 decreasing in the planned output صار قول 280 يعني 139 00:10:47,740 --> 00:10:51,960 هم كانوا مخططين يزودوا الناتج من 100 ل 300 لكن ما 140 00:10:51,960 --> 00:10:57,620 زادش ل 300 نزل او زاد من 100 ل 280 هذا الفرق ال 141 00:10:57,620 --> 00:11:01,920 decreasing بيسمو crowding out crowding out عارفين 142 00:11:01,920 --> 00:11:03,700 إيش يعني مزحمة 143 00:11:05,480 --> 00:11:09,980 مزحمة للخلف بالنتج يعني بمعنى ان النتج صار في اندي 144 00:11:09,980 --> 00:11:14,560 تزاحمات نتيجة ان ال interest rate طلع أثر على ال 145 00:11:14,560 --> 00:11:18,680 investment بالسلب وبالتالي صار في نزول في 146 00:11:18,680 --> 00:11:22,140 aggregate output ومن ثم هذا بيسموه crowding out 147 00:11:22,140 --> 00:11:26,820 effect تمام؟ اه شباب؟ اذا if you would like to 148 00:11:26,820 --> 00:11:32,540 analyze or to analyze yes the effect of 149 00:11:35,230 --> 00:11:37,850 Interest or the relationship between interest rate 150 00:11:37,850 --> 00:11:41,430 and the planned investment خلينا نعمل رسم هيك لل 151 00:11:41,430 --> 00:11:46,190 interest rate و ل planned investment This is R I 152 00:11:46,190 --> 00:11:49,610 and as you know that the relationship between R 153 00:11:49,610 --> 00:11:53,110 and I is what؟ Negative صح؟ أيوه 154 00:11:56,330 --> 00:12:01,030 هذا I وهذا رقم الاستثمار المخطط مظبوط؟ طيب اين هو 155 00:12:01,030 --> 00:12:04,110 الانترست الوحيد؟ وين كان الانترست الوحيد؟ هايه 156 00:12:04,110 --> 00:12:09,490 ماشي مع رسمها هيك هاي الانترست الوحيد او الانترست 157 00:12:09,490 --> 00:12:14,430 الوحيد اللي هو ال R1 مظبوط؟ هايها هذا R1 وهذا E1 158 00:12:14,430 --> 00:12:19,470 تطابق ما بين هذا وهذا؟ وهذا الانترست المخطط I1 159 00:12:22,360 --> 00:12:25,560 when the money demand increased شو اللي صار ال 160 00:12:25,560 --> 00:12:30,720 interest rate increased to 161 00:12:30,720 --> 00:12:38,440 E2 this is R2 and I has declined to I2 نفس الشغل 162 00:12:38,440 --> 00:12:42,060 اللي بنحكي فيه هذا هايو increasing in R leads to a 163 00:12:42,060 --> 00:12:45,720 decreasing in I مظبوط then aggregate expenditure 164 00:12:45,720 --> 00:12:51,010 declined and then Y declinedتمام؟ وهذا الانزول هنا 165 00:12:51,010 --> 00:12:55,930 اسمه crowding out تمام؟ مين مش فاهم عيدله؟ لأن 166 00:12:55,930 --> 00:13:01,950 المحاضرة هدف الجزء منها في الامتحان انا 167 00:13:01,950 --> 00:13:06,270 later on بحكيلك كيف بيجي السؤال بس بدي تفهم the 168 00:13:06,270 --> 00:13:08,970 most important issue is to understand what I say 169 00:13:08,970 --> 00:13:13,330 اه؟ طيب اذا let us summarize 170 00:13:27,080 --> 00:13:32,380 الحكومة تستخدم سياسة مالية توسعية باستخدام استخدام 171 00:13:32,380 --> 00:13:32,820 استخدام استخدام استخدام استخدام استخدام استخدام 172 00:13:32,820 --> 00:13:34,680 استخدام استخدام

استخدام استخدام استخد 178 00:13:43,580 --> 00:13:46,280 which leads to increasing aggregate output and 179 00:13:46,280 --> 00:13:50,040 then increasing the aggregate income مظبوط؟ طيب 180 00:13:50,040 --> 00:13:53,840 increasing the aggregate income leads to 181 00:13:53,840 --> 00:13:58,100 increasing the money demand which leads to a 182 00:13:58,100 --> 00:14:01,460 rightward shifting of the money demand curve صح؟ 183 00:14:01,460 --> 00:14:07,770 هى لأ و بدى أرجع شويه هيكUsing an expansion of 184 00:14:07,770 --> 00:14:09,790 fiscal policy means increasing the government 185 00:14:09,790 --> 00:14:12,130 spending leads to increasing aggregate expenditure 186 00:14:12,130 --> 00:14:15,550 from aggregate expenditure of the black line one 187 00:14:15,550 --> 00:14:19,610 to the aggregate expenditure two So Y has 188 00:14:19,610 --> 00:14:23,470 increased from Y one to Y two بصبو يعني if suppose 189 00:14:23,470 --> 00:14:29,850 من مية لتلت مية طب بعد هيك The increasing in money 190 00:14:29,850 --> 00:14:34,750 demand leads to increasing the interest rateصح؟ هي 191 00:14:34,750 --> 00:14:39,550 ال interest rate طلع من R1 to R2 وهي ينبين عندى 192 00:14:39,550 --> 00:14:42,850 هنا بال relationship between R and I او the 193 00:14:42,850 --> 00:14:46,830 planned investment curve هي increasing في ال 194 00:14:46,830 --> 00:14:48,910 interest rate طب عارفين احنا ال increasing في ال 195 00:14:48,910 --> 00:14:50,790 interest rate هو ال cost of borrowing وبالتالي ال 196 00:14:50,790 --> 00:14:56,310 investment بده يقل with a small amount اللي أثر 197 00:14:56,310 --> 00:14:59,830 تلقائيا على ال aggregate expenditure ومن ثم ال 198 00:14:59,830 --> 00:15:04,610 aggregate Yaggregate output or aggregate income 199 00:15:04,610 --> 00:15:09,250 واللي رجع الناتج بدل ما كنا مخططين زوده من Y1 ل Y2 200 00:15:09,250 --> 00:15:16,850 رح رجع شوية من Y2 ل Y3 هذا اسمه crowding out بس 201 00:15:16,850 --> 00:15:25,210 طبعا طيب سؤال امتى بيكونش فيه تأثير لسعر الفائدة 202 00:15:25,210 --> 00:15:29,110 على الاستثمار على ال investmentيعني لما بيزيد ال 203 00:15:29,110 --> 00:15:36,770 interest rate ال investment مازيدش بيجلش اه 204 00:15:38,770 --> 00:15:42,610 السؤال بيقول انه احنا بنقول انه ال crowding out او 205 00:15:42,610 --> 00:15:46,130 مشكلة ال crowding out ظهرت وين لما .. لما ارتفع 206 00:15:46,130 --> 00:15:49,870 سعر الفائدة نزل استثمار ومن ثم نزل الناتج صح؟ وهذا 207 00:15:49,870 --> 00:15:53,310 الإشكالي اللي احنا مخطط ان ازود ال Y ال Inca ال 208 00:15:53,310 --> 00:15:56,930 aggregate output من Y1 ل Y2 وبالتالي نتيجة انه 209 00:15:56,930 --> 00:16:01,790 حساسية ال sensitivity لل investment لسعر الفائدة 210 00:16:01,790 --> 00:16:05,620 هو اللي أثر على ان النتج يرجع لورا، مظبوط؟بس 211 00:16:05,620 --> 00:16:08,580 السؤالي أنا خليني أسأل السؤال وبعدين أخد منكم 212 00:16:08,580 --> 00:16:14,680 السؤال بيقول امتى جايك محمد هلأ السؤال بيقول انه 213 00:16:14,680 --> 00:16:18,300 ممكن نرفع سعر الفائدة بس الاستثمار ماينزلش وقتاش 214 00:16:18,300 --> 00:16:22,500 وبالتالي مافيش تأثير على ان ال income ال aggregate 215 00:16:22,500 --> 00:16:24,680 expenditure ينزل yes تاني 216 00:16:30,040 --> 00:16:35,560 لما يزيد نسبة ال government تمام بمقدار نسبة ال I 217 00:16:35,560 --> 00:16:40,920 نزولها؟ لأ السؤال يه انه وقتهش انه ال interest 218 00:16:40,920 --> 00:16:44,760 rate لما بيزيد ال investment ما بينزلش يسمحوا .. 219 00:16:44,760 --> 00:16:50,020 exactly thank you very much indeed yes yes لما 220 00:16:50,020 --> 00:16:53,060 بيكون ملحانة ال investment ال plant investment 221 00:16:53,060 --> 00:16:56,140 vertical line ها يو خليه vertical line شو اللي 222 00:16:56,140 --> 00:17:02,110 بيصير؟ارفع ال interest rate ال investment مينزلش 223 00:17:02,110 --> 00:17:11,530 خلّي ال investment curve vertical line خلّي عمودي 224 00:17:11,530 --> 00:17:19,810 هيك exactly خلّي ال investment هيك vertical line 225 00:17:19,810 --> 00:17:25,850 so this is R I وين ال interest rate الرئيسي؟ هيه 226 00:17:25,850 --> 00:17:31,810 this is A1وارتفع .. this is I1 R1 ارفع ال interest 227 00:17:31,810 --> 00:17:37,070 rate زود ال interest rate to R2 ال investment I2 228 00:17:37,070 --> 00:17:43,030 there is no decreasing in I عشان هيك لأ بتصير 229 00:17:43,030 --> 00:17:47,310 بتصير عشان هيك بيكون مافيش crowding out في حالة 230 00:17:47,310 --> 00:17:53,170 انه if the investment curve is vertical line معنى 231 00:17:53,170 --> 00:17:57,610 الكلام انه الاستثمار مش حساس لسه على الفئدة صح؟ 232 00:17:58,970 --> 00:18:02,670 مظبوط؟ or the investment is not respond for the 233 00:18:02,670 --> 00:18:07,910 interest rate مظبوط؟ مافيش استجابة للارتفاعات في 234 00:18:07,910 --> 00:18:11,750 سعر الفدع تأثير على الاستثمار so in this case the 235 00:18:11,750 --> 00:18:16,270 crowding out equals what؟ zero exactly عشان هيك مش 236 00:18:16,270 --> 00:18:18,550 هيرجع تاني ينزل aggregate expenditure 237 00:18:21,820 --> 00:18:24,420 مفيش .. على .. it depends you have to analyze you 238 00:18:24,420 --> 00:18:27,460 have to collect data او information about the 239 00:18:27,460 --> 00:18:31,000 investment and interest rate و تشوف بالاخر احنا 240 00:18:31,000 --> 00:18:35,800 بندرس cases على كيف بدي اخليه جايكلك كيف اخليه 241 00:18:35,800 --> 00:18:40,680 thank you على سؤالك ازملكم بيسأل سؤال انه كيف بدي 242 00:18:40,680 --> 00:18:45,380 اخلي ال investment او اللي هو ال investment مش 243 00:18:45,380 --> 00:18:50,010 حساس او بدي ألغي تأثير سعر الفائدةعارفين شو بدى 244 00:18:50,010 --> 00:18:58,010 أعمله؟ بدى أرجع بس للرسم هاي و أحل لك المشكلة this 245 00:18:58,010 --> 00:19:03,610 is 246 00:19:03,610 --> 00:19:11,070 I مظبوط and this is R and I تمام according to our 247 00:19:11,070 --> 00:19:13,570 assumption this is E1 248 00:19:16,760 --> 00:19:27,480 E2 R1 R2 I1 I2 في عنده increasing في ال R و 249 00:19:27,480 --> 00:19:35,500 decreasing في ال I عشان ألغي تأثير to cancel the 250 00:19:35,500 --> 00:19:38,480 effects of interest rate على سعر الفائد ده شو بعمل 251 00:19:38,480 --> 00:19:45,870 الحل اللي قالك بسيطةالـ money supply كيف 252 00:19:45,870 --> 00:19:52,230 تعمل تزوّد ال money supply خلاص اعمل rightward 253 00:19:52,230 --> 00:19:55,490 shifting لـ money supply curve هيو جيبه هنا هيك 254 00:19:55,490 --> 00:19:56,690 خلصنا ثبت 255 00:20:02,110 --> 00:20:06,990 عشان ألغي تأثير ألغي crowding out زود ال money 256 00:20:06,990 --> 00:20:10,790 supply شو صار ال interest rate نزل وبالتالي بطل 257 00:20:10,790 --> 00:20:14,370 فيه التقى تأثير ال interest rate على ال investment 258 00:20:14,370 --> 00:20:21,420 Yes عبداللهبالتأكيد، بالتأكيد، لكي نحل المشكلة من 259 00:20:21,420 --> 00:20:25,420 المجتمع، المشكلة من المجتمع، لدينا أو الشركة 260 00:20:25,420 --> 00:20:32,440 الأساسية لتحفة المال، أو لإستخدام منظمة تحفيزية، 261 00:20:32,440 --> 00:20:39,380 نعم عبداللهOkay ماشي بس أنا the question is how 262 00:20:39,380 --> 00:20:43,560 could we solve the crowding out effect يعني كيف 263 00:20:43,560 --> 00:20:48,700 بدي ألغى تأثير هذا تأثير الارتفاع في سعر الفائدة؟ 264 00:20:50,220 --> 00:20:56,820 هذا الرد ع سؤالك وصلة تمام So as we mentioned that 265 00:20:56,820 --> 00:21:00,320 using an expansionary fiscal policy as you see 266 00:21:00,320 --> 00:21:03,720 leads to increasing aggregate expenditure then 267 00:21:03,720 --> 00:21:06,660 aggregate output aggregate income increasing money 268 00:21:06,660 --> 00:21:09,480 demand increasing interest rate decreasing I and 269 00:21:09,480 --> 00:21:13,740 so on So the crowding out problem or the crowding 270 00:21:13,740 --> 00:21:19,610 out ethic has been created whenوين تولدت فكرة أو 271 00:21:19,610 --> 00:21:22,810 مشكلة لـ crowding out when the government use an 272 00:21:22,810 --> 00:21:26,610 expansionary fiscal policy صح؟ طيب، بدأ أروح 273 00:21:26,610 --> 00:21:32,930 أستخدم let us use a contractionary fiscal policy 274 00:21:32,930 --> 00:21:36,750 يعني أنا بدأ أستخدم إشي معاكس بمعنى إنه أنا بدأ 275 00:21:36,750 --> 00:21:42,110 أستخدم contractionary fiscal policy by decreasing 276 00:21:42,110 --> 00:21:45,170 the government spending and or increasing the 277 00:21:45,170 --> 00:21:48,870 taxes خلينا نشوفوبدأ أشوف التأثير على ال three .. 278 00:21:48,870 --> 00:21:51,870 على ال three .. ال analysis على ال three diagrams 279 00:21:51,870 --> 00:22:08,150 هدول تمام؟ طيب So 280 00:22:08,150 --> 00:22:12,390 let's use a contractionary fiscal policy 281 00:22:12,390 --> 00:22:16,090 expansionary 282 00:22:28,960 --> 00:22:38,820 سياسة مالية انكماشية by decreasing the government 283 00:22:38,820 --> 00:22:46,840 spending or increasing the taxesيا بدنا ننزل انفاق 284 00:22:48,650 --> 00:22:51,690 maybe ممكن يكون في علنا inflation عشان هيك 285 00:22:51,690 --> 00:22:55,010 استخدموا سياسة مالية انكماشية بدهم يخفضوا ال 286 00:22:55,010 --> 00:22:59,030 inflation عشان هيك راحوا يستخدموا سياسة مالية 287 00:22:59,030 --> 00:23:02,930 انكماشية تمام؟ يمكن هذا ال reason هذا السبب او 288 00:23:02,930 --> 00:23:06,230 اللي يعني اللي اللي خلهم يستخدموا contractionary 289 00:23:06,230 --> 00:23:09,070 fiscal policy خلينا نشوف شو ال effects او ال 290 00:23:09,070 --> 00:23:12,750 impact of this policy on the goods market والمoney 291 00:23:12,750 --> 00:23:19,660 market وال investment in general تمام؟ soas you as 292 00:23:19,660 --> 00:23:23,600 we mentioned that the decreasing in g leads to a 293 00:23:23,600 --> 00:23:26,660 decreasing in aggregate expenditure because g is 294 00:23:26,660 --> 00:23:29,040 part of aggregate expenditure so a decreasing in g 295 00:23:29,040 --> 00:23:31,620 leads to a decreasing in aggregate expenditure or 296 00:23:31,620 --> 00:23:37,660 a decreasing in aggregate demand هدوين 297 00:23:37,660 --> 00:23:43,320 بوديني على decreasing in y aggregate output or 298 00:23:43,320 --> 00:23:46,930 aggregate income مظبوطالـ Decreasing في الـ 299 00:23:46,930 --> 00:23:50,810 aggregate output أو الـ Income شو معناه ده؟ leads 300 00:23:50,810 --> 00:23:56,450 to a decreasing of money demand صح؟ 301 00:23:56,450 --> 00:23:59,890 decreasing في ال money demand we have a leftward 302 00:23:59,890 --> 00:24:04,770 shifting of the money demand curve خليني أشوفها 303 00:24:04,770 --> 00:24:08,340 أولا بدي أوديني هذاطب هتقول بيوديني ان ال interest 304 00:24:08,340 --> 00:24:12,500 rate هينزل صح؟ so the leftward shifting of money 305 00:24:12,500 --> 00:24:16,820 demand curve leads to a decreasing in R which 306 00:24:16,820 --> 00:24:22,400 means increasing of I و 307 00:24:22,400 --> 00:24:28,200 اللي بيوديني ع وين increasing of 308 00:24:28,200 --> 00:24:31,220 aggregate expenditure with a small amount 309 00:24:34,010 --> 00:24:41,690 ومن ثم increasing في ال Y with a small هذا اسمه 310 00:24:41,690 --> 00:24:46,310 crowding in شوفت العكس؟ يعني كوننا مخططين ننزل 311 00:24:46,310 --> 00:24:50,150 الناتج يعني 312 00:24:50,150 --> 00:24:54,730 من رقم لرقم، من 300 ل100، لكن نتيجة التزاحمات اللي 313 00:24:54,730 --> 00:24:59,330 صارت أو تأثير الإيجاب لسعر الفائدة زود الناتج 314 00:24:59,330 --> 00:25:07,520 بمقدار بسيطلا بيبقى لها مستمرة بس بس you have to 315 00:25:07,520 --> 00:25:10,920 understand the analysis يعني هذا اللي بديك تفهمه 316 00:25:10,920 --> 00:25:15,480 اللي بدك إذا بتمشي في السلسلة بتروح آه يعني إذا 317 00:25:15,480 --> 00:25:20,900 بدي أمشي بالتحليل بروح على سوق ال labor market و 318 00:25:20,900 --> 00:25:23,600 بروح على سوق ال bonds و الهذا بس أنا مش رايح 319 00:25:23,600 --> 00:25:28,810 باتجاهات هذه يعني للتبسيط هي التحليل التبعيبس 320 00:25:28,810 --> 00:25:31,250 تفهموا .. يعني it's far enough for you to 321 00:25:31,250 --> 00:25:34,570 understand this يدرس advanced لطلاب التخصص في 322 00:25:34,570 --> 00:25:39,050 الاقتصاد حتى يدرس في المصدر كمان مش بس .. let's 323 00:25:39,050 --> 00:25:42,330 come back here to analyze the contractual fiscal 324 00:25:42,330 --> 00:25:48,230 policy هذا 325 00:25:48,230 --> 00:25:53,470 في ال goods market و .. and this is in the money 326 00:25:53,470 --> 00:26:05,160 marketand this is the investment curve نيجي هان y 327 00:26:05,160 --> 00:26:12,800 aggregate expenditure one c 328 00:26:12,800 --> 00:26:18,600 plus i plus g نقول one تمام؟ لأن أنا بدي نزل ال g 329 00:26:18,600 --> 00:26:31,540 and this is a one y oneتمام؟ طيب الـ decreasing في 330 00:26:31,540 --> 00:26:34,800 الـ G أمل decreasing في ال aggregate expenditure 331 00:26:34,800 --> 00:26:37,480 so we have a downward shifting في ال aggregate 332 00:26:37,480 --> 00:26:41,160 expenditure function صح؟ في عندى نزول في ال 333 00:26:41,160 --> 00:26:46,300 aggregate expenditure function وليه صارت هيك؟طبعا 334 00:26:46,300 --> 00:26:51,480 هذا بيكون Parallel للتاني بشكل موازي So this is 335 00:26:51,480 --> 00:26:56,040 aggregate expenditure to C plus I plus G2 اللي هو 336 00:26:56,040 --> 00:27:01,580 فيه اندزول في ال government spending تمام؟ طيب So 337 00:27:01,580 --> 00:27:06,960 we have a new equilibrium which point E2 and this 338 00:27:06,960 --> 00:27:15,770 is Y2 Suppose أنه كنا بدنا ننزل الناتج من 400400$ 339 00:27:15,770 --> 00:27:22,410 ل 150$ هذا هو 340 00:27:22,410 --> 00:27:26,630 المخطط التبعي ان انا بدأ نزل الناتج من 400$ ل 150$ 341 00:27:26,630 --> 00:27:36,190 طيب شو نصار لنذهب لـ money market هذا 342 00:27:36,190 --> 00:27:42,150 ال money supply one money demand one and this is 343 00:27:42,150 --> 00:27:50,530 the QMR أين المناطق المتساويه هنا هذا E1 وهذا R1 344 00:27:50,530 --> 00:27:54,730 اتباه طيب ال decreasing اللي صار في ال aggregate 345 00:27:54,730 --> 00:28:00,490 expenditure شو يعمل في النتج نزل from Y1 to Y2 صح 346 00:28:00,490 --> 00:28:05,050 ومن ثم ال aggregate income نزل هايه this is 347 00:28:05,050 --> 00:28:10,450 aggregate outputor a great income ومن ثم ال money 348 00:28:10,450 --> 00:28:15,610 demand decline صح؟ so there is a leftward shifting 349 00:28:15,610 --> 00:28:23,070 in the money demand curve ايو مدتو exactly شو صار 350 00:28:23,070 --> 00:28:28,110 في ال interest rate نزل exactly so we have this is 351 00:28:28,110 --> 00:28:33,190 a2 r2 we have a decreasing in the interest rate 352 00:28:34,310 --> 00:28:45,670 خلّينا نرسم منحنا ال investment this is R I where 353 00:28:45,670 --> 00:28:53,210 is the original interest rate هاي و هيك this is E1 354 00:28:53,210 --> 00:28:59,330 R1 we have a decreasing in R and this is I1 355 00:29:02,430 --> 00:29:09,710 we have a decreasing in R to E2 R2 we have a 356 00:29:09,710 --> 00:29:17,030 decreasing in R and increasing in I مظبوط؟ 357 00:29:17,030 --> 00:29:21,570 صح ولا لأ؟ هدا وين وداني؟ ال increasing in I leads 358 00:29:21,570 --> 00:29:25,830 to an increasing in aggregate expenditure and then 359 00:29:25,830 --> 00:29:29,470 Y with a small amount اللي هو ال crowding in إذا 360 00:29:29,470 --> 00:29:34,520 خلينا نرسمه بال bloom lineهيو شفتوا قداش نزل 361 00:29:34,520 --> 00:29:37,720 بالأول بدي أرجع أرفعه بحاجة بسيطة اللي هو ال 362 00:29:37,720 --> 00:29:43,520 aggregate expenditure هنا هيو 363 00:29:43,520 --> 00:29:48,980 there is a new equilibrium point صح هيا suppose it 364 00:29:48,980 --> 00:29:58,890 was E تلاتة this is Y3 شو معناها ده؟Crowding in 365 00:29:58,890 --> 00:30:07,850 exactly كنا مخططين نزل الناتج من Y1 ل Y2 راح نزل 366 00:30:07,850 --> 00:30:11,750 بس من Y1 ل Y3 اللي هو المسافة هاي، مظبوط ولا لأ؟ 367 00:30:11,750 --> 00:30:16,150 يعني لأنه رجع زاد الناتج شوية
