This paper proposes a generalization of the single output stochastic production frontier model. The generalization allows estimation of production frontiers and distance functions (technical efficiency) for multiple output technologies using cross section or panel data on inputs and outputs.

The present paper consists of two closely related parts: one which outlines a normative criterion for evaluating the legitimacy of constitutional change and one which specifies a particular proposal of a constitution. The criterion used stems directly from the "pragmatic" brand of...

This set of lecture notes constitutes a self contained overview of the martingale based theory of interest rates. The lectures were given by the author at the 1996 CIME Summer School on Mathematical Finance, in Bressanone, Italy. The topics covered include: Bond markets, interest rates,...

Swedish import price determination is investigated using disaggregated monthly data from 1980:1 to 1995:05 for eight different industries. The cointegration analysis indicates two cointegrating relations, in all industries, between import prices, the exchange rate, world market prices and...

In this paper we discuss the efficiency properties of insurance markets where supplementary private insurance is allowed to exist together with a compulsory government insurance plan. Our main conclusion, which is contrary to both those of Besley (1989) and Selden (1993), is that in a simple...

in a bargaining game over the provision of a public good, two principals appoint one agent each to carry out the bargaining. Each agent has preferences over the outcome. Two institutional set-ups are studied, each with a different level of authority given to the agents. By authority is here...

Lagrange multiplier (LM) test statistics are derived for testing a linear moving average model against an asymmetric moving average model and an LM type test against an additive smooth transition moving average model. The latter model is introduced in the paper. The small sample performance of...

This paper identifies and evaluates the impact of structural and economic reforms in India on the behavior and performance of Swedish multinational affiliates in that country. The paper identifies certain changes in the behavior and performance which support the goals of economic reform,...

Long run purchasing power is tested on 16 OECD countries using data from 1960 to 1994, PPP is rejected for some countries (Canada, Japan, Switzerland, Austria, Italy and Spain) and not rejected for other (Sweden, France, Holland and the United Kingdom). For the latter countries, impulse response...

This paper presents a network model incorporating customer satisfaction into efficiency and productivity measures. The network consists of a production node and a consumption node and offers flexibility in modelling the production and consumption process. Allocation of input resources to...
