Econ 240 C Lecture 13
CA Budget Crisis • What is Happening to UC? • UC Budget from the state General Fund
UC Budget • Econ 240A Lab Four • New data for Fiscal Year 2003-04 • Governor’s Budget Summary 2003-04 • released January 2003 • http://www.dof.ca.gov/
UC Budget, 1968-69 through 2003-04 4000 3500 3000 2500 Millions $ 2000 1500 1000 500 0 68-69 70-71 72-73 74-75 76-77 78-79 80-81 82-83 84-85 86-87 88-89 90-91 92-93 94-95 96-97 98-99 00-01 02-03 Fiscal Year
CA Budget Crisis • What is happening to the CA economy? • CA personal income
CA Budget Crisis • How is UC faring relative to the CA economy?
UC Budget Vs. CA Personal Income, 1968-69 through 2003-04 4 3.5 3 2.5 UC Budget, $B 2 1.5 1 0.5 0 0 200 400 600 800 1000 1200 1400 CA Personal Income, $B
CA Budget Crisis • What is happening to CA state Government? • General Fund Expenditures?
CA Budget Crisis • How is CA state government General Fund expenditure faring relative to the CA economy?
CA Size of Government Vs. CA Economy, 1968-69 through 2003-04 90 80 70 60 CA General Fund Expenditure $B 50 40 30 20 10 0 0 200 400 600 800 1000 1200 1400 CA Personal Income $ B
Long Run Pattern Analysis • Make use of definitions: • UCBudget = (UCBudget/CA Gen Fnd Exp)*(CA Gen Fnd Exp/CA Pers Inc)* CA Pers Inc • UC Budget = UC Budget Share*Relative Size of CA Government*CA Pers Inc
What has happened to UC’s Share of CA General Fund Expenditures? • UC Budget Share = (UC Budget/CA Gen Fnd Exp)
CA Budget Crisis • Estimate of UC’s Budget Share for 2003-04: 4.25 % or 4.85% • will the legislature lower UC’s share?
What has happened to the size of California Government Expenditure Relative to Personal Income? • Relative Size of CA Government = (CA Gen Fnd Exp/CA Pers Inc)
California Political History • Proposition 13 • approximately 2/3 of CA voters passed Prop. 13 on June 6, 1978 reducing property tax and shifting fiscal responsibility from the local to state level • Gann Inititiative (Prop 4) • In November 1979, the Gann initiative was passed by the voters, limit real per capita egovernment expenditures
CA Budget Crisis • Estimate of the relative size of the CA government: 6.75% vs. 5.35 %?
CA Budget Crisis: Pattern Estimate of UCBudget • UC Budget = UC Budget Share*Relative Size of CA Government*CA Pers Inc • Midpoint estimate: • UC Budget = 0.0455*.0605*1176.4 $B =$ 3.24 B estimate • Governor’s proposal in January: $ 3.04 B • So, $ 3.24 B is probably too optimistic
Econometric Estimates • Linear Trend Estimate • UCBUD(t) = a + b*t +e(t) • about same as Governor’s January proposed $ 3.04 B • Lucky?
Econometric Estimates • Logarithmic (exponential trend) • lnUCBUD = a + b*t +e(t) • simple exponential trend will over-estimate UC Budget
Econometric Estimate • Dependence of UC Budget on CA Personal Income • UCBUD(t) = a + b*CAPY(t) + e(t) • looks like a linear dependence on income will overestimate the UC Budget for 2003-04
Econometric Estimates • How about a log-log relationship • lnUCBUD(t) = a + b*lnCAPY(t) + e(t) • autocorrelated residual • fitted lnUCBUD(2003-04) = 1.18630 • $3.27 B • actual (Governor’s Proposal) = 1.11142 • $3.04B
Econometric Estimates • Try a distributed lag Model of lnUCBUD(t) on lnCAPY(t) • clearly lnUCBUD(t) is trended (evolutionary) so difference to get fractional changes in UC Budget • likewise, need to difference the log of personal income
Estimate ARONE Model for dlncapy(t) • Orthogonalize dlncapy and save residual • need to do transform dlnucbud • dlnucbud(t) = h(Z)*dlncapy(y) + resid(t) • dlncapy(t) = 0.732*dlncapy(t-1) + N(t) • [1 - 0.732Z]*dlnucbud(t) = h(Z)* [1 - 0.732Z]*dlncapy(t) + [1 - 0.732Z]*resid(t) • i.e. w(t) = h(Z)*N(t) + residw(t)
Distributed Lag Model • Having saved resid as res[N(t)] from ARONE model for dlncapy • and having correspondingly transformed dlnucbud to w • cross-correlate w and res
Distributed lag model • There is contemporary correlation and maybe something at lag one • specify dlnucbud(t) = h0 *dlncapy(t) + h1 *dlncapy(t-1) + resid(t)
Try a dummy for 1992-93, the last recession, this is the once and for all decline in UCBudget mentioned by Granfield • There is too much autocorrelation in the residual from the regression of lnucbud(t) = a + b*lncapy(t) + e(t) to see the problem • Look at the same regression in differences
