We develop new methods for representing the asset-pricing implications of stochastic general equilibrium models. We provide asset-pricing counterparts to impulse response functions and the resulting dynamic value decompositions (DVDs). These methods quantify the exposures of macroeconomic cash flows to shocks over alternative investment horizons and the corresponding prices or investors’ compensations. We extend the continuous-time methods developed in Hansen and Scheinkman (2012) and Borovi?ka et al. (2011) by constructing discrete-time, state-dependent, shock-exposure and shock-price elasticities as functions of the investment horizon. Our methods are applicable to economic models that are nonlinear, including models with stochastic volatility. 相似文献

I present proofs for the consistency of generalized method of moments (GMM) estimators presented in Hansen (1982). Some basic approximation results provide the groundwork for the analysis of a class of such estimators. Using these results, I establish the large sample convergence of GMM estimators under alternative restrictions on the estimation problem. 相似文献

Based on firm level data from 16 Sub-Saharan African countries we show how three different measures of credit constraints lead to three different estimates of gender differences in manufacturing firms’ credit situation. Using a perception based credit constraint measure female owned firms appear relatively more constrained than male owned firms. Using formal financial access data we find no gender effect. Finally, using direct information on credit constraints, male owned small firms appear disadvantaged. Furthermore we show a strong size gradient in the gender gap for the two measures for which we find significant gender differences. 相似文献

Quotas are frequently used in the management of renewable resources and emissions. However, in many industries there is concern about their basic effectiveness due to non-compliance. We develop an enforcement model of a quota-regulated resource and focus on a situation with significant non-compliance and exogenous constraints on fines and enforcement budget. We propose a new enforcement system based on self-reporting of excess extraction and explicit differentiation of inspection rates depending on compliance history. We use differentiated inspections to induce firms to self-report excess extraction. This system increases the effectiveness of the quota by allowing the regulator to implement a wider range of aggregate extraction targets than under traditional enforcement, while ensuring an efficient allocation of extraction. In addition, inspection costs can be reduced without reductions in welfare. 相似文献

This paper analyzes how a reduction in trade costs influences the possibility for firms to engage in international cartels, and hence how trade liberalization affects the degree of competition. We consider a particular intra‐industry trade model amended to allow for firms producing differentiated products. Our main finding is that trade liberalization may have an anti‐competitive effect. We find that there is no unique relation between a reduction in trade costs and the degree of competition. When products are differentiated, a lowering of trade costs is pro‐competitive if trade costs are initially high, but anti‐competitive if trade costs initially are low. Hence, trade policy is not necessarily a substitute for competition policy. 相似文献

Has the Single Market for public procurement had the expected effects after six years in progress? The following article attempts to answer this question by first presenting alternative theoretical approaches to analysing the EU liberalisation of the public procurement market and then confronting these with the result of an empirical analysis. 相似文献

This paper expands the standard analysis of female labor supply to permit preference heterogeneity by using a finite mixture
model. Using the extended model, we obtain theory consistent results whereas a traditional model produces a negative substitution
effect. We use our model to illustrate the labor supply effects of a tax reform, corresponding to 1983–1992 changes in the
Swedish income-tax schedule. The results shows an expected reduction in tax revenues of about 17%. Finally, we use Monte Carlo
simulations and show that our proposed mixture model is robust towards different misspecifications.

Professors Hansen and Kelley suggest practical guidelines for implementing course evaluation systems, drawing upon their experience at the University of Wisconsin. They develop a model to conceptualize course evaluations in the context of the professor's decision-making framework, focusing upon the allocation of time between teaching and research. Costs and benefits associated with collecting evaluations are considered, and ways of minimizing the former and maximizing the latter are suggested. 相似文献
