Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Problem Overview • Effects of Stimulus bill on employment • Multipliers to find effect on GDP • Related GDP change to unemployment change • Timeline of changes • Indicators that will mark recovery • Additional stimulus needed
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Plan 1: Assumptions • The multipliers from Mark Zandi and Paul Krugmanare accurate • Diminishing marginal returns apply to the stimulus multipliers • These diminishing returns can be modeled through an exponential function: multnew=(multoriginal)*(.9)^(money spent/$100 billion) • No other major economic changes will affect employment
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Plan 1: Analysis • “Biggest Bang for the Buck” • GDP effect = (money spent)*(mult)*(.9)^(money spent/100 billion) • % Change in GDP = (GDP effect) / (14.2646 trillion) • % Change in unemployment = (% Change in GDP) / 2.899
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Plan 1: Results • Infrastructure Spending and Aid to State Governments will have the greatest effect on GDP and unemployment. • Food Stamps and Unemployment Insurance Benefits will have the greatest effect per billion dollars spent. • The net effect on GDP will be $845 billion. • The net effect on nominal GDP will be 5.96% of GDP.
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Plan 1: Timeline • Most money will be spent by 2011 • $719 billion • Over half in 2nd year • Will see effects as soon as 6 months later
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Economic Results • A mix of leading indicators and fundamental statistics in the economy • Manufacturing Sector and Consumer Sentiment are historic leading indicators • An upturn in the Housing Sector is necessary for a recovery • Lowering unemployment and raising GDP are the ultimate goals

Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion GDP Change
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Modeling the Relationship Between Real GDP and the Unemployment Rate • “Okun’s Law” • For every 1% increase in unemployment, there is a 2-3% • decrease in GDP • GDP = V * (I + C) • This equation was used to calculate a more accurate • multiplier
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Assumptions Made • On a large time scale, unemployment is the only factor affecting real GDP • Other factors affecting GDP will affect unemployment rates in a similar manner, thus eliminating its effects in the long run • The unemployment compensation in the district of St. Louis, MO is representative of the compensation throughout the entire country • CA, TX, FL, NY were used to represent the populated states of the West Coast, Southwest, Southeast, and Northeast respectively; ID represents the sparsely populated states of the Midwest, West, South • Workers are either single or part of a married couple filing separate tax returns
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion GDP = V * (I + C) Calculating I, the Income remaining after Federal and State Tax • Part A: Calculating I, the taxable income • 3 Major Sectors of American Industry Experiencing Significant Job • Loss: Manufacturing, Construction, Financial Activities • The following calculations were performed for each sector • Umonth1 – Umonth2 = ∆U, the number of newly unemployed in consecutive months • Ew * 4 = EM • EM * 12 = EY • -EY * ∆U = EY lost due tounemployment
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion GDP = V * (I + C) Calculating I, the Income remaining after Federal and State Tax • Part B: Applying Federal Taxes to the Calculated values of I • IRS income tax brackets: $4386.25 + 0.25 (EY lost - $31850) = Tlost • -Tlost * ∆U = TF,lost • This represents the amount of federal tax revenue lost due to • unemployment between consecutive months
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion GDP = V * (I + C) Calculating I, the Income remaining after Federal and State Tax • Part C: Applying State Taxes to the Calculated values of I • Different states have different taxing policies. Using the 5 states chosen in our “Assumptions” section, we calculated an average tax rate to apply to all taxable income, regardless of the location. This average tax rate was 6%. • (EY - TF ) * ∆U * 0.06 = TS, lost • Part D: Calculating The Amount of Income Lost due to Unemployment • (EY,lost ) - (TF,lost ) - (TS,lost ) = $ Lost in Sector • Part E: Calculating I, the Income Remaining after Federal and State Taxes • ($ Lost in Manufacturing) + ($ Lost in Construction) + ($ Lost in Financial Activities) = I
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion GDP = V * (I + C) Calculating I, the Income remaining after Federal and State Tax • Total C in St. Louisx Total Pop. in U.S. = Total C in U.S. • Pop. in St. Louis • Total C in U.S. = C per Unemployed Worker • Total U in U.S. • (∆ nonfarm payroll employment) * (C per worker) • = ∆ Unemployment Compensation
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion GDP = V * (I + C) Calculating V, the Velocity of Money • V = (PQ) / M • P is the price level • Q is the GDP • M is the money supply • Note: a 2001 chain-typed index was used for GDP, M1 money supply and price level
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion GDP = V * (I + C) Calculating GDP Loss • Returning to the equation we had formulated, we plugged in the values we had obtained for I, C, and V • We divided our calculated GDP loss by the percent change in nonfarm payroll for the years 2000 through 2009; this value represents the ratio between GDP loss and unemployment rates • We averaged these values to reduce irregularities • This gave us 2.899 as the ratio between a 1% increase in unemployment and the % decrease in GDP.
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Second Plan: Goals • Reduce unemployment to 5% from peak of 9.1% • Requires $1.8 trillion or 11.9% increase in GDP • Likely to be greater than first, due to diminishing marginal returns • 4.1% decrease in unemployment=11.9%/2.899 • Allocates money most effectively
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Second Plan: Assumptions • Can treat both plans as simultaneous effects • Multipliers have diminishing marginal return of an exponential 0.9 per $100 billion • Only top 6 multipliers need to be considered • 1.02*0.9^(520/100) = 0.59 • $5 billion increments is sufficient
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Second Plan: Algorithm Initialize money allocation • Added multipliers sequentially • High to low • Set high bounds by previous runs Calculate net effect Compare to best plan Loop over all money allocations
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Second Plan: Results
Introduction Stimulus Plan 1 Economic results Okun’s Law Stimulus Plan 2 Conclusion Conclusion • First stimulus plan: • Costs $800 billion and leads to $850 billion effect • Majority spent and takes effect in first 3 years • Economic indicators will indicate when economy recovers and the effects of the stimulus • Every 2.899% change in GDP reduces unemployment by 1% • Second stimulus plan: • $960 billion additional stimulus plan needed • Will reduce unemployment from 9.1% to 5%
