In the context of multivariate regression (MLR) and simultaneous equations (SE), it is well known that commonly employed asymptotic test criteria are seriously biased towards over-rejection. In this paper, we propose exact likelihood based tests for possibly nonlinear hypotheses on the...

We consider the bootstrap unit root tests based on autoregressive integrated models, with or without deterministic time trends. A general methodology is developed to approximate asymptotic distributions for the models driven by integrated time series, and used to obtain asymptotic expansions for...

In this paper we analyze the interaction of two disciplinary mechanisms: competition and reputation. We first study a dynamic model of monopolistic competition with experienced goods (i.e., quality is observed after goods are purchased). When market power is high enough, reputation results in...

This paper develops a two-country, two-sector general equilibrium business cycle model with nominal rigidities featuring deviations from the law of one price. We show that a model with such building blocks can quantitatively account for the empirical fact that, of the statistical properties of...

Teen out-of-wedlock mothers have lower education and earnings than peers who have children later. This study uses the National Educational Longitudinal Survey of 1988 (NELS) to examine the extent to which the apparent effects of out-of-wedlock teen fertility are not causal, but are due to...

In a two-period, double moral hazard model with incomplete contracting, this paper explores the relationship between revenue sharing and control rights. Specifically, we endogenize the allocation of both the income rights and the control rights and show why the two are often bundled together in...

The architecture of public decision making in the world is being changed through processes of "economic integration" and of "decentralization". Some policy decisions are now taken at a higher level (i.e., monetary policy in Europe, trade policy in part of South America), while others are taken...

We compute the value of a firm that pays its cash flows each period through share repurchases in a dynamic environment where personal taxes are paid on realized capital gains and dividends. These results provide a measure of the personal tax advantages of equity financing relative to debt...

This study analyses the transmission of monetary policy in Germany for the EMS period in the framework of a structural vector error correction model (S-VECM) analysis. Cointegration relations derived from economic theory are tested within the Johansen framework in the first step. Three stable...

It is well known that vertical integration can change an upstream producer's incentive to supply the integrated firm's downstream rivals. However, it has not been noticed that vertical integration also changes these rivals' incentive to choose suppliers. Once this is recognized, some important...
