This paper develops methods for evaluating marginal policy changes. We characterize how the effects of marginal policy changes depend on the direction of the policy change, and show that marginal policy effects are fundamentally easier to identify and to estimate than conventional treatment...

This paper examines the perspectives of Russian gas exports to Western Europe and the strategic options of the CIS gas transiting countries, namely Ukraine and Belarus. The development of a new transit corridor through Belarus (the Yamal-Europe pipeline), depriving Ukraine of its former...

This paper reviews the literature on the effects of low steady-state inflation on wage formation, focusing on four different effects. First, under low inflation, downward nominal wage rigidity (DNWR) may prevent real wage cuts that would have happened had inflation been higher. Second, wages...

We examine international cooperation on technological development as a supplement to, or an alternative to, international cooperation on emission reductions. R&D should be increased beyond the non-cooperative level if (i) the technology level in one country is positively affected by R&D in other...

We study a search model with employment protection legislation. We show that if the output from the match is uncertain ex ante, there may exist a discriminatory equilibrium where workers with the same productive characteristics are subject to different hiring standards. If a bad match takes...

Recent rounds of GATT and later WTO have advocated widespread tariffication, meaning that existing non-tariff barriers be converted into import equivalent tariffs. From an economic point of view, the effects of such tariffication are not entirely clear. The paper presents a general equilibrium...

We consider a model of an information network where nodes can fail and transmission of information is costly. The formation of paths in such networks is modeled as the Nash equilibrium of an N player routing game. The task of obtaining this equilibrium is shown to be NP-Hard. We derive...

Rank-order tournaments are usually modeled simultaneously. However, real tournaments are often sequentially. We show that agents' strategic behavior significantly differs in sequential tournaments compared to simultaneous tournaments. In a sequential tournament, under certain conditions the...

An empirical model of managers' demand for agency goods is derived and estimated using the Almost Ideal Demand System of Deaton and Muellbauer (AER 1980). As in Jensen and Meckling (JFE 1976), we derive managers' demand for agency goods by maximizing a managerial utility function where managers...

This paper investigates the effects of temporal aggregation when the aggregation frequency is variable and possibly stochastic. The results that we report include, as a particular case, the well-known results on fixed-interval aggregation, such as when monthly data is aggregated into quarters. A...
