This paper provides insights into the apparent seesaw between the generation of theoretical versus empirical economics research over time. A dynamic model considers the incentives of researchers to focus on empirical versus theoretical papers. It yields the main characteristics of the...

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...

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...

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...

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...

This paper studies a three player hierarchical differential game (with a large country, a small country, and a terrorist organization), to analyze the actual European refugee situation. Terrorists may enter Europe as refugees, taking advantage of the Open Door Policy, to attack both countries....

This paper derives a dynamic path of ongoing terror attacks as a function of terrorists' capacity and a target government's counterterror capacity. The analysis provides several novel insights and characterizations. First, the effect of counterterror policy is limited. Second, proactive...

We study the interaction between monetary and fiscal policies in a Ramsey-Sidrauski model augmented with environmental capital. Equilibrium solutions are studied through the "Green Golden Rule". Despite the non-separability of money in utility and intertemporally nonseparable preferences, money...

Private sector research and development (R&D) in food processing has seen a growing share of agricultural R&D. This paper analyzes market and technological links between farmer-entrepreneurs and food processing firms. It is shown that processing sector R&D tends to display explosive cycles. To...
