We study the impact of social capital in both simple theoretical and em- pirical model with the main assumption is the price of physical capital is a decreasing function of social capital. In our theoretical model, there exists a critical value such that ffrm will not invest in social capital if...

In this note, we present a wealth model of a two-country economy where ffnancial assets and goods are traded. We consider the case where the agents are risk neutral, a very common assumption in ffnance in order to have explicit solutions for prices, and in particular in international ffnance for...

This note provides an intuitive and simple proof of the existence of equilibrium in an incomplete ffnancial economy with numeraire assets, when the preferences are represented by concave, strictly increasing functions..

We consider a model with an finite number of states of nature where short sells are allowed.

In this paper we use the CMM model (Chakravorty et al., 2006) in discrete time and obtain more results concerning the exhaustion time of Non-Renewable Resource (NRE), the dynamic regimes of energy prices, of the stocks of pollution. We show that NRE is exhausted in finite time and is directly...

Upon introducing natural resources, both renewable and non-renewable, into an endogenous growth framework with R&D, this paper derives the transitional dynamics of an economy towards its long-run equilibrium. Using the Euler - Lagrange framework, this paper has succesfully gured out the optimal...

The main contribution of the paper is to provide a weaker non-satiation assumption than the one commonly used in the literature to ensure the existence of competitive equilibrium. Our assumption allows for satiation points in the set of individually feasible consumptions, provided that the...

We set up a theoretical framework to discuss the impact of trade liberalization and R&D policies on domestic exporting firms' incentive to innovate and social welfare. In this framework, exporting firms invest in R&D to reduce their production costs and, in return, receive R&D subsidies from the...
