This paper studies the expulsion of Jews from Spain in 1492. This forced migration process is addressed with a model that blends demographic, religious and macroeconomic features. The optimal migration path is derived. It is shown that a large portion of the Sephardim community fled the country...

The Solow condition is examined in an intertemporal model that blends the shirking and the turnover models of efficiency wages with managerial supervision. It is shown that the Solow condition does not hold when shirking and turnover costs are considered. The Solow condition can be a possible...

We derive a very general ("Janus") money demand function, which reflects backward and forward-looking habit formation. This generality offers an explanation for the breakdown of money-demand functions and policy relevance of monetary aggregates. Integrating our Janus money demand into a...

We confront five stylized facts related to sovereign default: 1) the presence of serial defaulters; 2) the prevalence of partial over complete default; 3) the counter-cyclicality of default; 4) non-linearity of sovereign spreads; and 5) heterogeneous outcomes among serial defaulters. In a model...

Using the political-economic history of the development of telephony during the 1870s as a backdrop, this paper studies a two-player Tullock contest that includes both research effort (R&D) and legal effort (i.e., rent-seeking effort). The two types of efforts complement each other and...

This paper presents an extension of the two-period Samaritan's Dilemma in order to analyze the potential for foreign aid to promote freedom. An example is the United States' recent opening towards Cuba. It is shown that a donor nation's dual concern for economic reforms and greater freedoms can...

This paper adapts the Ethics of Spinoza into the Ramsey growth model and shows that the way people conceive and understand life, related to emotions of joy and sorrow, affects economic performance. The model has multiple equilibria: The Spinoza solution — optimism — leads to greater capital...

We derive the Green Golden Rule (GGR) in the Habit Formation (HF) and Anticipation of Future Consumption (AFC) frameworks. Since consumption is the key variable of GGR, time non-separabilities in preferences over consumption streams, given by the AFC and HF, may have important impacts on the...

Considering the sequential nature of nascent entrepreneurship and business ownership, this paper examines the propensities of academic entrepreneurs to be business owners. A theoretical model sets up the empirical analysis based on survey data from a large German public research institute....
