The recent literature on optimal taxation may be seen as attempting to clarify the structure of the arguments advanced to support changes in the tax system, tracing the implications of taxes and quantifying (analytically) the trade-offs between the various objectives of tax policy. This literature has examined the optimal structure for particular types of taxation taken in isolation, such as th...

Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, compute the corresponding premiums, and thereby reduce asymmetric information. An efficient risk classification system generates premiums that fully reflect the expected cost associated with each class of risk characteristics. This is known as financial equity. In t...

The paper studies the impact of an equity transaction tax (ETT) on financial and real variables in a DSGE model with two types of financial frictions: (1) financial intermediaries facing a leverage constraint; (2) noise shocks that lead to the emergence of nonfundamental equity trade. The ETT depresses the demand for equity and hence increases the cost of capital; this then affects firms’ inves...

This paper infers the terms of trade effects of Free Trade Agreements (FTAs) implemented in the 1990s. We estimate large FTA effects on bilateral trade volume in 2 digit manufacturing goods from 1990-2002, using panel data gravity methods to resolve two way causality. The terms of trade changes implied by these volume effects are deduced for 40 countries plus a rest-of-the-world aggregate using...

The impact of Trade Points on corporate performance depends on assumptions about returns to scale, types of games played, and size of gains in demand and revenues v i s á v i s costs. Specifically: (i) in a world of profitmaximizing firms, when the contribution of Trade Points to total revenues exceeds the additional costs, Trade Points help both small firms and large ones with the size of gain...
