The paper investigates the long-run consequences of a phase-out of nuclear energy for the Swiss economy. We apply the CITE model, a CGE model with fully endogenous growth, and complement it with a bottom-up model. We find that the nuclear phase-out can be achieved at relatively low costs, even...

In 2008, governments in many countries embarked on large fiscal expenditure programmes, with the intention to support the economy and prevent a more serious recession. In this study, the overall impact of a substantial increase in fiscal expenditure is considered by providing a novel analysis of...

Governments purchase everything from airplanes to zucchini. This paper investigates whether the technological intensity of government demand affects corporate R&Dactivities. In a quality-ladder model of endogenous growth, we show that an increase in the share of government purchases in high-tech...

The credibility of standard instrumental variables assumptions is often under dispute. This paper imposes weak monotonicity in order to gain information on counterfactual outcomes, but avoids independence or exclusion restrictions. The outcome process is assumed to be sequentially ordered,...

This paper explores semi-monotonicity constraints in the distribution of potential outcomes, first, conditional on an instrument, and second, in terms of the response function. The imposed assumptions are strictly weaker than traditional instrumental variables assumptions and can be gainfully...

The goal of this paper is to use a semiparametric reduced form model to estimate the effects of various tuition subsidies. This approach expands on the tuition subsidy example in Ichimura and Taber (2000) in a number of dimensions. It has become common practice in the empirical literature to...

Four alternative but related approaches to empirical evaluation of policy interventions are studied: social experiments, natural experiments, matching methods, and instrumental variables. In each case the necessary assumptions and the data requirements are considered for estimation of a number...

This chapter studies the microeconometric treatment-effect and structural approaches to dynamic policy evaluation. First, we discuss a reduced-form approach based on a sequential randomization or dynamic matching assumption that is popular in biostatistics. We then discuss two complementary...

Investment liberalizing countries are often concerned that cross-border mergers & acquisitions, in contrast to greenfield investments, might have an adverse effect on domestic firms and consumers. However, given that domestic assets are sufficiently scarce, we identify a preemption effect and an...
