The paper sets out theory and evidence for the equilibrium determination of the nominal interest rate. We test the cash-in-advance economy using US postwar data and find cointegration of the interest rate, inflation, unemployment and the money supply, using either M2 or M1 monetary aggregates,...

The paper introduces for the most frequently used three- dimensional panel data sets several random effects model specifications. It derives appropriate estimation methods for the balanced and unbalanced cases and deals with some extensions as well. An application is also presented where the...

We study the problem of torts in a framework where a firm's accident adversely impacts all firms in the industry because of the presence of industry reputation effects. Industry reputation effects lead to interdependence among firms and give rise to strategic firm behavior. We characterize the...

We document that administrative trade costs of per shipment nature (documentation, customs clearance and inspection) lead to less frequent and larger-sized shipments, i.e., more lumpiness, in international trade. We build a model where consumers have heterogeneous preferences for the arrival...

I propose an emissions trading scheme which mimics the upcoming third phase design of the European Union Emissions Trading Scheme, with auction as initial allocation method. Risk-averse polluters and speculators, participating in the scheme, respond idiosyncratically to an economy-wide shock. I...

We study trade policy in a two-sector Krugman (1980) trade model, allowing alternatively for production subsidies, import tariffs or export subsidies. For each instrument, we consider the unilateral trade policy without retaliation, the Nash solution and the cooperative solution and contrast...

The paper shows how a dynamic neoclassical AS-AD can be derived and used to describe business cycles and growth trends to undergraduates. Derived within the Ramsey-Cass-Koopmans (RCK) model, the AS-AD is the stationary equilibrium of the deterministic dynamic general equilibrium framework....

Market wages reflect expected productivity by using signals of past performance and past experience. These signals are generated at least partially on the job and create incentives for agents to choose high-profile and highly visible tasks. If agents have private information about the...

We consider a functional parameter called the conditional average treatment effect (CATE), designed to capture heterogeneity of a treatment effect across subpopulations when the unconfoundedness assumption applies. In contrast to quantile regressions, the subpopulations of interest are defined...

This paper proposes a practical method for estimating consumer lock-in effects from firm-level data. The method compares the behavior of already contracted consumers to the behavior of new consumers, the latter serving as a counterfactual to the former. In panel regressions on firms' incoming...
