This paper attempts to provide empirical evidence of the positive definiteness of the mean income effect matrix, a sufficient condition for market demand to satisfy the law of demand derived by Härdle, Hildenbrand and Jerison [HHJ(1991)]. Increasing heterogeneity in spending of populations of...

This paper uses a model of trade in vertically differentiated products to examine the effects of excessive wage increases (i.e. above productivity) on the volume of commodity imports. The model predicts that for commodities, in which the country has comparative advantage in high quality...

Using a unique enterprise-level data set, which covers the regions Moscow City, Chelyabinsk, Krasnoyarsk and Chuvashia and the three sectors manufacturing and mining, construction and trade and distribution, we estimate Russian labour demand equations for the year 1997. The most important...

This paper shows an alternative specification of the demand functions of both total imports and the imports of capital goods for Brazil. The set up is based on the conjecture that a variable expressing the availability of foreign exchange should be included in these import functions. Our...

We study the identification and estimation of preferences in hedonic discrete choice models of demand for differentiated products. In the hedonic discrete choice model, products are represented as a finite dimensional bundle of characteristics, and consumers maximize utility subject to a budget...

I develop a technique useful for obtaining more precise estimates of demand and supply curves when constrained to market-level data. It augments the estimation routine with data on the average characteristics of consumers that purchase different products. I apply the technique to the automobile...

This paper analyzes optimal portfolio decisions of long-horizon investors with undiversifiable labor income risk and exogenous expected retirement and lifetime horizons. It shows that the fraction of savings optimally invested in stocks is unambiguously larger for employed investors than for...

Matching uncertain demand with capacities is notoriously hard. Operationsmanagers can use mix-flexible resources to shift excess demands to unused capacities.To find the optimal configuration of a mix-flexible production network, aflexibility design problem (FDP) is solved. Existing literature...
