In this paper we introduce basic notions of new economic model where preference relations on commodities set are represented by a group action on Euclidean space instead of utility function. Conditions that ensure the existence of individual demand functions and a general equilibrium in the...

In this paper we extend the benchmark model of Diamond-Mortensen-Pissarides in a two-sector general equilibrium framework by introducing a frictionless segment of the labour market. The two sectors are the frictionless informal sector and the frictional formal sector where match friction is the...

Using a general equilibrium model with endogenous growth, I show that risk to human capital leads to a “Value” premium in equity returns. In particular, firms with relatively more firm-specific human capital or more positive covariance between asset growth and returns on human capital are...

The objective of this study is to examine the stability of a general equilibrium model in which trade takes place at non-equilibrium prices. Quantity constraints are perceived by the traders and effective demands and supplies are explicitly derived from utility and profit maximization....

In this note I discuss the condition for indeterminacy in the context of search models with increasing returns in the matching technology. Building on the theoretical framework set forth by Giammarioli (2003), I argue that increasing returns with respect to vacancies at the aggregate level is...

This theoretical note shows that developing countries possess an inherent shock-absorbing mechanism that stems from their peculiar institutional characteristics that can lessen the gravity of detrimental welfare consequence of exogenous terms-of-trade disturbances in terms of a two-sector,...

We extend the benchmark model of DMP in a two-sector general equilibrium framework by introducing a frictionless segment of the labour market. We also examine the effects of trade reforms and labour market reforms on equilibrium rate of unemployment and wage inequality in our stylitzed economy....

This paper shows that developing countries possess an inherent shock-absorbing mechanism that stems from their peculiar institutional characteristics and can lessen the gravity of detrimental welfare consequence of exogenous terms-of-trade disturbances in terms of a two-sector, full-employment...

This article is a response to the recent “Worrying Trends in Econophysics” critique written by four respected theoretical economists [1]. Two of the four have written books and papers that provide very useful critical analyses of the shortcomings of the standard textbook economic model,...

A general equilibrium model, that incorporates endogenous production and local housing markets, is developed in order to explain the price relationship among human capital, housing, and stocks, and to uncover the role of housing in asset pricing. Housing serves as an asset as well as a durable...
