We show that a multiple-unit descending-price auction in which the clock is not reset after each sale may be faster and yield more stable prices than an efficient alternative, thus providing sellers a rationale for using it in practice. 相似文献

Public health spending is introduced into an endogenous growth model to examine the effect of a tax reform on the growth and learning time. Unlike previous studies, the calibrated model produces an increase in the learning time, consistent with the US data. 相似文献

We examine the effect of a federally-funded local infrastructure spending program on local unemployment rates. To address the likely funding endogeneity problem, we exploit variation in spending due to pork-barreling, and find that higher government expenditure on roads substantially reduces local unemployment. 相似文献

The relationship between income distribution and economic growth has long been an important economic research subject. Despite substantial evidence on the negative impact on long-term growth of inequality in the literature, however, there is not much consensus on the specific channels through which inequality affects growth. The empirical validity of two most prominent political economy channels - redistributive fiscal spending and taxes, and sociopolitical instability - has recently been challenged. We advance a new political economy channel for the negative link between inequality and growth, a fiscal policy volatility channel, and present strong supporting econometric evidence in a large sample of countries over the period of 1960-2000. Our finding also sheds light on another commonly observed negative relation between macroeconomic volatility and growth. We carefully address the robustness of the results in terms of data, estimation methods, outlier problem, and endogeneity problem that often plague the standard OLS (ordinary least squares) regression. 相似文献

Recent research has demonstrated that while government expenditures are countercyclical in most industrialized countries, they tend to be procyclical in developing countries. We develop a dynamic political-economy model to explain this phenomenon. In the model, public expenditures provide insurance to uninsured households, and optimal fiscal policy is countercyclical. The introduction of a political friction, in which successive governments disagree on the desired distribution of public spending, can lead to procyclical fiscal policies. Numerical simulations of the model allow us to compare quantitatively the relative role of common explanations for fiscal procyclicality. We conclude that political distortions in the fiscal process can explain fiscal procyclicality better than other common explanations, such as borrowing constraints and macroeconomic volatility. 相似文献

This paper studies the efficiency of competitive equilibria in environments with a moral hazard problem and unobserved states, both with retrading in ex post spot markets. The interaction between private information problems and the possibility of retrade creates an externality, unless preferences have special, restrictive properties. The externality is internalized by allowing agents to contract ex ante on market fundamentals determining the spot price or interest rate, over and above contracting on actions and outputs. Then competitive equilibria are equivalent with the appropriate notion of constrained Pareto optimality. Examples show that it is possible to have multiple market fundamentals or price-islands, created endogenously in equilibrium. 相似文献

Under study are games in which players receive private signals and then simultaneously choose actions from compact sets. Payoffs are measurable in signals and jointly continuous in actions. This paper gives a counter-example to the main step in Cotter?s [K. Cotter, Correlated equilibrium in games with type-dependent strategies, J. Econ. Theory 54 (1991) 48-69] argument for correlated equilibrium existence for this class of games, and supplies an alternative proof. 相似文献

We analyze forecasts of car sales in the U.S. and forecasts of car registrations in Japan. We document a substantial heterogeneity of forecasts, and we show that, based on traditional criteria, forecasts are neither rational nor unbiased. We also report that forecasters anti-herd, that is, forecasters seem to intentionally scatter their forecasts around a consensus forecast. We further show that cross-sectional heterogeneity of forecasts with regard to anti-herding transmits onto cross-sectional heterogeneity of forecast accuracy. Specifically, we document that forecasters who herd provide more accurate forecasts than their colleagues who anti-herd. 相似文献

We study the effect of the size of the welfare state on demographic trends in OECD member countries. Exploiting exogenous variation in public social spending, due to varying degrees of political fractionalization (i.e., the number of relevant parties involved in the legislative process), we show that an expansion in the welfare state increases fertility, marriage, and divorce rates with a quantitatively stronger effect on the marriage rate. We conclude that the welfare state supports family formation in the aggregate. Further, we find that the welfare state decouples marriage and fertility, and therefore alters the organization of the average family. 相似文献
