In this paper I question whether the risk weights in the advanced (IRB) approach of the Basel 2 regulation are appropriate, on a strictly theoretical ground. The major concern is that the model behind the regulation considers defaults only at the end of the time horizon for which capital is to...

In this chapter I argue that as a response to the introduction of capital requirements in the form of risk weights investors might potentially choose riskier portfolios than before the regulation – this is, presumably, not what the regulation intends to achieve. That is, while regulation most...

In this paper I present a method for the simulation of the default of such loans that have two important properties: they are seasoned – maybe even being at different points of the seasoning curve – and they evolve in an asset-value based framework. This latter model allows us to introduce...

In this paper I present a simple model through which I examine how large unwanted outcomes in a process subject to one’s decisions can be avoided. The paper has implications for decision makers in the field of economics, financial markets and also everyday life. Probably the most interesting...

Intrinsically trustworthy agents never cheat. A society's willingness to trust and the quality of its institutions have their origins in the intrinsic trustworthiness of its citizens. Trustworthiness is the basis for maximizing output in economic exchange and in explaining differences in...

The instrumental variables strategy is commonly employed in empirical research. For correct inference using this econometric technique, the instruments must be perfectly exogenous and relevant. In fact, the standard t-ratio test statistic used in this context yields unreliable and often...

This paper introduces endogenous capital income tax rates as in Schmitt-Grohe and Uribe (1997), into the overlapping generations model with endogenous labor and consumption in both periods of life (e.g., Cazzavillan and Pintus, 2004). In contrast with the previous result that the existence of...

Israel’s policies regarding Lebanon have been dependent on public opinion, which is very volatile. The citizens of Israel did not favor the occupation of the security zone in South Lebanon because of the Four Mothers movement, and it influenced the government to withdraw military forces...

This research attempts a theoretical and quantitative analysis of authoritarian regimes enduring in the developing countries. We attempt computer visualization of the model developed by Acemoglu and Robinson in order to derive an empirical hypothesis easily. There is a reason for us to accept...

This document presents a Macroeconomic Consistency Model for a dollarized economy such as Ecuador. Based on a simply accounting framework that combined the social accounting matrix with the flow of funds, we integrate the different sectors of the economics through a matrix of income,...
