This article proposes semi-parametric least squares estimation of parametric risk-return relationships, i.e. parametric restrictions between the conditional mean and the conditional variance of excess returns given a set of unobservable parametric factors. A distinctive feature of our estimator...

Abstract: We determine the incentives for compatibility provision of firms that produce network goods with different intrinsic qualities. We consider the case in which both firms have the power to veto compatibility and the case in which none has this power. We obtain that if consumers have a...

I develop a novel view of comparative advantage that collectively explains (i) the effect of distance and GDP per capita on the price composition of trade, and (ii) the systematically higher trade-to-GDP ratio of rich countries. There are two types of goods, which offer different scopes for...

This paper examines monetary policy responses to oil price shocks in a small open economy that produces traded and non-traded goods. When only labor and oil are used in production and prices are sticky in the non-traded sector the behavior of ination, the nominal exchange rate, and the relative...

Fiscal foresight---the phenomenon that legislative and implementation lags ensure that private agents receive clear signals about the tax rates they face in the future---is intrinsic to the tax policy process. This paper develops an analytical framework to study the econometric implications of...

The well-known approximation of the difference between the arithmetic average and geometric average returns as one-half of the variance of the underlying returns is reexamined using Jensen’s Inequality. The ”defect” in Jensen’s Inequality, is given an exlicit formula in terms of the...

Minimum dropout age (MDA) laws have been touted as effective policies to bring dropouts off streets and into classrooms. One question to better understand the costs and benefits of these laws is: to what extent do MDA laws displace crime from streets to schools? This research expands the...

We construct a dynamic general equilibrium model to analyze the effects of large energy subsidies in a small open economy. The model pays special attention to domestic energy production and consumption, trade in energy at world market prices, as well as private and public sector production...

The dynamics of a welfare maximizing, heterogeneous agent, one sector optimal Ramsey model is analyzed assuming two agents, each with a distinct discount factor and log utility. Production is Cobb-Douglas. Explicit time varying policy functions are derived, one for each period. A Twisted...
