In this paper some results on the problem of computing optimal designs for discriminating between rival models are provided. Using T-optimality for two rival models a compound criterion is developed to discriminate between more than two models. Surprising results arise when T-optimal designs are...

In this paper we test the empirical evidence of an impact of privatisation on output in the UK , through macroeconomic transmission channels. While most privatisation studies focus on microeconomic shocks, namely at firms' level, we are interested to see whether a large scale privatisation...

A procedure for the construction of an indicator in the presence of structured missing data is proposed. In particular, we face the problem of creating a ‘measure’ of the damage degree of valuable historical-architectonical buildings on the basis of the observation of several ordinal...

Two-sided network effects in card payment systems are analysed under different market structures, e.g., competition, one-sided monopoly, bilateral monopoly and duopoly; with and without an interchange fee; for the so-called Baxter case of non-strategic merchants. A partial ranking of market...

This paper compares the effect of economic integration on industry location for a small country that goes ahead with an integration process, such as the European, and a country adopting a wait and see strategy. Theoretical results, derived from a three-region new economic geography model, are...

This paper models how drug lords in final destination countries respond to two types of government anti-drug policies: demand and supply oriented. Supply policies (crop eradication, interdiction, etcetera) are modeled in line with the previous literature, that is, they increase production costs....

The purpose of this study is to examine the impact of gender segregation on wages using matched employer-employee private-sector data from Sweden. The questions that we are interested in examining are two-fold. Has the effect of gender segregation on the gender wage gap been overestimated and...

This paper examines the optimal instrument choice to control emissions under uncertainty. A hybrid regulation mechanism is developed that contains cap-and-trade, emissions taxes and socalled safety valves as special cases. This makes it possible to examine optimal policy choice and the resulting...

This paper takes on the issue of ‘Prices vs. Quantities’, see Weitzman (1974), applied to environmental regulations under uncertainty. It is shown that, from an efficiency point of view, it is generally preferable to divide the economy into two parts, one regulated through a tax and the...

Decentralised decisions, to a bureau with a given budget, about the production of public goods is analysed within a general equilibrium model with a representative agent and no pure profits. It is shown that decentralisation (i) does not necessarily imply aggregate production effciency and (ii)...
