output dynamics in real business cycles models the time series literature reports two stylized facts about output dynamics in the united states gnp growth is positively autocorrelated and gnp appears to have an important trend reverting component this paper investigates whether current real business cycle rbc models are consistent with these stylized facts many rbc models have weak internal propagation mechanisms and must rely on external sources of dynamics to replicate both facts models that incorporate labor adjustment costs are partially successful they endogenously generate positive autocorrelation in output growth but they need implausibly large transitory shocks to match the trend reverting component in output

government purchases and real interest rates this paper examines the dynamic impact of government purchases in a simple general equilibrium model with both durable and nondurable consumer goods as well as productive capital the model generates perhaps surprising results in particular increases in government purchases are shown to cause reductions in real interest rates the model thus provides a possible explanation for the observed behavior of real interest rates around wars copyright 1987 by university of chicago press

willingness to pay and the distribution of risk and wealth willingness to pay wtp most economists believe is an appropriate benefits metric for government expenditure and regulatory policies that reduce risks to human life it depends however on the distribution of risk and wealth currently society s expenditures overemphasize concentrated risks say after the fact treatment as opposed to prevention a dead anyway effect complements excess attention to intense interests in explaining this our normative criterion for spending on risk reduction is what a rational albeit uninsured individual confronting lotteries on future risks to life and wealth would choose for himself this requires correcting wtp to eliminate the dead anyway effect but continues to reflect that wealth enhances the utility of living

incentives for helping on the job theory and evidence recent advances in incentive theory stress the multidimensional nature of agent effort and specifically cases where workers affect one anothers performance through helping efforts this article models helping efforts as determined by the compensation package and task allocation the model is tested with australian evidence on reported helping efforts within work groups the evidence consistently supports the hypothesis that helping efforts are reduced while individual efforts are increased when promotion incentives are strong piece rates and profit sharing appear to have little effect on helping efforts while task variety and helping efforts are positively correlated

defense spending cutbacks and real interest rates in the neoclassical one sector and two sector models abstract this paper uses the neoclassical one sector and two sector models to examine the behavior of real interest rates in response to cutbacks on defense spending on capital goods and army personnel it is demonstrated that while a permanent decline in defense spending on capital goods and military personnel leaves the term structure unaffected in the one sector model the two sector model predicts that the short and medium term real interest rates rise to give a downward sloping yield curve when the capital goods producing sector is relatively labor intensive

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

temporary and permanent government spending in an open economy some evidence for the united kingdom abstract this paper investigates the effects of government spending changes on a small open economy in an intertemporal substitution framework if agents internalize the government s budget constraint temporary and permanent spending have different implications for wealth and consequently different effects on output and the balance of trade estimation of these effects isolates the different channels through which government spending can influence economic activity main findings for the united kingdom are that government spending i crowds out private spending ii is directly productive and iii when rising permanently leads to a negative wealth effect which induces a large rise in work effort

sectoral shifts and cyclical unemployment a substantial fraction of cyclical unemployment is better characterized as fluctuations of the frictional or natural rate than as deviations from some relatively stable natural rate shifts of employment demand between sectors of the economy necessitate continuous labor reallocation since it takes time for workers to find new jobs some unemployment is unavoidable this paper presents evidence that most of the unemployment fluctuations of the seventies unlike those in the sixties were induced by unusual structural shifts within the u s economy simple time series models of layoffs and unemployment are constructed that include a measure of structural shifts within the labor market these models are estimated and a derived natural rate series is constructed

stochastic trends and economic fluctuations are business cycles mainly the result of permanent shocks to productivity this paper uses a long run restriction implied by a large class of real business cycle models identifying permanent productivity shocks as shocks to the common stochastic trend in output consumption and investment to provide new evidence on this question econometric tests indicate that this common stochastic trend cointegration implication is consistent with postwar u s data however in systems with nominal variables the estimates of this common stochastic trend indicate that permanent productivity shocks typically explain less than half of the business cycle variability in output consumption and investment copyright 1991 by american economic association

government spending interest rates prices and budget deficits in the united kingdom 1701 1918 abstract the british data from the early 1700s through wwi provide an unmatched opportunity for studying temporary changes in government purchases temporary increases which appeared mainly as wartime spending raised long term interest rates but significantly increased the growth rates of money and prices only during suspensions of the gold standard 1797 1821 and 1914 1918 temporary changes in military spending accounted for the bulk of budget deficits over the sample of more than 200 years i found only two major non war deficits one associated with compensation payments to slaveowners in 1835 1936 and the other with a dispute over the income tax in 1909 1910 interest rates did not react much to these exogenous deficits

an equilibrium model of sectoral reallocation this paper constructs a two period two sector model in which there are permanent sectoral shocks it analyzes the equilibrium path of individual labor supply sectoral employment and duration of unemployment in response to these shocks equilibrium allocations are shown to be easy to characterize and comparative statics results are provided

the aggregate effects of sectoral reallocations abstract can a one time permanent change in the fundamentals behind the sectoral composition of the economy prompt an aggregate downturn can this downturn be non negligible even if one uses us data to determine the relative size of gross vs net job flows and the importance of job creation costs can one consider the military build down of the 1990s as a plausible cause for the 1990 1991 recession do sectoral reallocations generate responses that are qualitatively similar to productivity shocks we use a variant of the mortensen pissarides 1994 review of economic studies 61 397 415 job creation destruction model calibrate it to us labor market data and run experiments that suggest one can answer yes to all these questions

the cyclical behavior of marginal cost and price the author examines the cyclical behavior of price marginal cost margins for u s manufac turing after 1956 short run marginal cost is markedly procyclical this is primarily due to procyclical overtime payments incurred beca use employment is not perfectly flexible in most industries output price fails to respond to the cyclical movement in marginal cost so price marginal cost margins are markedly countercyclical the res ults contradict business cycle theories that explain low production i n a recession by a high real cost of producing they support theories that explain low production in a recession by the inability of firms to sell their output copyright 1987 by american economic association

corporations and ngos when accountability leads to co optation interactions between corporations and nonprofits are on the rise frequently driven by a corporate interest in establishing credentials for corporate social responsibility csr in this article we show how increasing demands for accountability directed at both businesses and ngos can have the unintended effect of compromising the autonomy of nonprofits and fostering their co optation greater scrutiny of ngo spending driven by self appointed watchdogs of the nonprofit sector and a prevalence of strategic notions of csr advanced by corporate actors weaken the ability of civil society actors to change the business practices of their partners in the commercial sector to counter this trend we argue that corporations should embrace a political notion of csr and should actively encourage ngos to strengthen downward accountability mechanisms even if this creates more tensions in corporate ngo partnerships rather than seeing ngos as tools in a competition for a comparative advantage in the market place corporations should actively support ngo independence and critical capacity

government spending interest rates and capital accumulation in a two sector model this paper investigates dynamic impacts of a temporary fiscal expansion in a two sector growth model if the expansion falls on consumption investment commodities capital accumulation can be either promoted or reduced and the short term interest rate unambigu ously rises if the expansion falls on consumption commodities capital accumulation is crowded out and the short term interest rate declines during the period of the fiscal expan sion it is also shown that fiscal spending on the consumption commodity can move the short and long term interest rates in opposite directions jel classification e43 e62 041

cyclical fluctuations and sectoral reallocation evidence from the psid abstract this paper documents the correlation between permanent sectoral reallocation and the business cycle using data from the michigan panel study of income dynamics we find that the outflow of workers from goods to services accelerates during recessions the flow from services to stable employment in surables accelerates during booms we also document the contribution of sectoral reallocation to total unemployment permanent switchers account for about a quarter of the total weeks of unemployment during booms this proportion rises to nearly 40 duing recessions

decomposition of hours based on extensive and intensive margins of labor abstract we decompose the underlying disturbances in total hours into three kinds disturbances that shift the level of employment in the long run those that change the sectoral composition of employment in the long run and those that cause temporary movement of hours our identifying restriction exploits the distinctive nature of the two margins of labor employment and hours per worker based on the postwar u s data we find that aggregate and sectoral disturbances are roughly equally important for the cyclical fluctuations of aggregate hours

compensation contracts do agency theory assumptions predict negotiated agreements this study examined how the ability to monitor an agent s actions and environmental munificence affect compensation contracts in principal agent dyads in a laboratory experiment we tested predict

the dilemma of accountability for professionals a challenge for mainstream management theories professional institutions are increasingly confronted by fiscal constraints and political pressures to improve and increase their accountability in a competitive consumer driven market accordingly the need to ensure efficiency and accountability is of strategic importance this article reports on a qualitative study of medical professionals that assessed the utility of financial incentives and external control methods derived from agency theory to ensure accountability of professionals the authors argue that approaches derived from stewardship and institutional theories can extend the principal agent perspective to sustain greater social and ethical accountability

an intertemporal model of saving and investment this paper characterizes a market economy with infinitely long lived consumers and value maximizing firms which face costs of adjustment for capital the temporary equilibrium of this economy is similar to the short run equilibrium of standard macroeconomic models consumption is a function of wealth investment is related to the value of firms equilibrium between aggregate demand and aggregate supply is achieved by the endogenous adjustment of the sequence of current and future interest rates the dynamic behavior of output consumption and investment in this economy is the same as in an optimal growth model with adjustment costs the paper shows this equivalence and then uses it together with the equivalence of taxes to technological shocks to study the dynamic effects of fiscal policy
