News--or foresight--about future economic fundamentals can create rational expectations equilibria with non-fundamental representations that pose substantial challenges to econometric efforts to recover the structural shocks to which economic agents react. Using tax policies as a leading example...

Aging populations in advanced economies are placing ever-increasing demands on government spending in the form of old-age benefits. Economies that have promised substantially more benefits than they have made provision to finance are heading into a prolonged era of fiscal stress. Unresolved...

We use a rational expectations framework to assess the implications of rising debt in an environment with a "fiscal limit." The fiscal limit is defined as the point where the government no longer has the ability to finance higher debt levels by increasing taxes, so either an adjustment to fiscal...

We develop a rational expectations framework to study the consequences of alternative means to resolve the "unfunded liabilities'' problem---unsustainable exponential growth in federal Social Security, Medicare, and Medicaid spending with no plan to finance it. Resolution requires specifying a...

This paper contributes to the debate about fiscal multipliers by studying the impacts of government investment in conventional neoclassical growth models. The analysis focuses on two dimensions of fiscal policy that are critical for understanding the effects of government investment:...

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...

Accommodating asymmetric information in a dynamic asset pricing model is technically challenging due to the problems associated with higher-order expectations. That is, rational investors are forced into a situation where they must forecast the forecasts of other agents (i.e., form higher-order...

This paper develops a dynamic asset pricing model with persistent heterogeneous beliefs. The model features competitive traders who receive idiosyncratic signals about an underlying fundamentals process. We adapt Futia's (1981) frequency domain methods to derive conditions on the fundamentals...

Das Thema Business Rules rückt seit einer Reihe von Jahren zunehmend in den Mittelpunkt des Interesses von IT-Anwendern, so dass es nahe liegt, sich diesem Ansatz verstärkt zuzuwenden. Mittels Business Rules kann betriebliche Anwendungssoftware und damit letztlich das Unternehmen schneller auf...
