In this paper, we construct alternative theoretical models for exchange rates by introducing additional risk factors, based on the volatility of macroeconomic fundamentals. The modified flexible-price monetary model is used to characterize the long-run equilibrium of exchange rates, while the...

Suppose that a group of agents having divergent expectations can share risks efficiently. We examine how this group should behave collectively to manage these risks. We show that the beliefs of the representative agent is in general a function of the group.s wealth level, or equivalently, that...

We consider an OLG economy with endogenous investment in human capital. Heterogeneity in individual human capital levels is generated by random innate ability. The production of human capital depends on each individual s investment in education. This investment decision is taken only after...

The degree of endemic volatility in the number of firms and establishments varies considerably across industries. Examining the within-industry range of variation (max.-min.) of the number of firms over our sample period, the low and high values across U.S. manufacturing industries are 4 and...

A sample of 11885 wage agreements, reached in the Canadian unionized sector during 1976-2000, a period of high as well as exceptionally low inflation and substantial fluctuations in nominal and real uncertainty, is used to study the determinants of key provisions of contracts such as their...

Restrictions on the risk-pricing in dynamic term structure models (DTSMs) can unleash the power of no-arbitrage by creating a tighter link between cross-sectional and time-series variation of interest rates. This paper presents a new econometric framework for estimation of affine Gaussian DTSMs...

Exchange of risks is considered here as a transferable-utility cooperative game. When the concerned agents are risk averse, there is a core imputation given by means of shadow prices on state-dependent claims. Like in finance, a risk can hardly be evaluated merely by its inherent statistical...

According to many observers, the world is currently getting riskier along many of its dimensions. In this paper we analyse how the welfare state, i.e., social insurance that works through redistributive taxation, should deal with this trend. We distinguish between risks that can be insured by...

We consider a firm that is subject to employment protection laws that limit the firm s ability to fire labor. In particular, we suppose that though a firm which shuts down can fire all its workers, it may fire no fewer. Compared to a firm that is subject to no employment protection, a firm...

Why do some U.S. states have higher levels of marital formation than others? This paper introduces an economic model wherin a state s representative individual may choose to marry in order to diversify his or her idiosyncratic income risk. The paper demonstrates that such a diversification...
