The market solution of a general R&D-based endogenous growth model is developed. The model is general in two respects: First, general formulations are used and restrictions are only introduced provided that these become necessary. Second, each factor of production (labour, capital and...

This paper sets up a simple AK-type growth model with heterogeneous consumption goods. It is shown that the (overall) intertemporal elasticity of substitution, the saving rate, and the growth rate of income unambiguously increase in the course of economic development. Moreover, the model offers...

This paper presents an inter-temporal model of individual behavior with uncertainty about marriage and divorce and which accommodates the possible presence of economies or diseconomies of scale from marriage. We show that a scenario of higher marriage rates and higher divorce rates will be...

This paper examines how banks can translate the potential of mobile phones into greater financial access for poor people. Although mobile phone operators have been able to use the mobile phone for mobile remittance and bill payment services in several countries, banks have had little success in...

We model a macroeconomy with stock flow consistent national accounts built from the local interactions of heterogenous agents (households, firms, bankers, and a government) through product, labor, and money markets in discrete time. We use this model to show that, without any restrictions on the...

This review article describes recent literature on asset allocation, covering both static and dynamic models. The article focuses on the bond--stock decision and on the implications of return predictability. In the static setting, investors are assumed to be Bayesian, and the role of various...

While credit risk transfer market dramatically increases the complexity of lender's incentive structure and above all reduces the incentives of the bank to monitor debtor, a ‘harsh' bankruptcy environment (as evidenced in the shift from the debtor controlled to creditor controlled...

Incumbent firms have two basic possibilities to improve their competitive position in the product market: investment in R&D and the creation of entry barriers to the disadvantage of potential rivals, e.g. through lobbying activities, campaign contributions, bribes or the adoption of incompatible...

This note proposes the Burr utility function. Burr utility is a flexible two-parameter family that behaves approximately power-like (CRRA) remote from the origin, while exhibiting exponential-like (CARA) features near the origin. It thus avoids the extreme behavior of the power family near the...

In this work we investigate how a number of crises have affected most of the stock markets in the world. First, we apply Time Series Factors Analysis (TSFA) in order to reduce the dimensionality of the series under study and obtain a lower number of factors that can be related to regions. Then...
