Innovator networks and regional knowledge base

Although network analysis has gained increasing attention over the last years, the literature on Regional Innovation Systems thus far has not embraced network methods. This study is an attempt to enrich the Regional Innovation System concept by applying social network methods to quantitatively assess the extent to which innovating actors in a region engage in systemic forms of knowledge exchange and collaboration. On the basis of a comparison of three rather different regional innovator networks, the paper suggests that regions with a strong knowledge base that are specialized in broad technology fields tend to have relatively fragmented network structures.     

Institutional Features of Schooling Systems and Educational Inequality: Cross‐Country Evidence From PIRLS and PISA

Educational opportunities determine the intergenerational mobility of human capital and affect the distribution of earnings on the labour market. This paper aims at explaining cross‐country differences in educational opportunities by features of schooling systems. The theoretical model predicts that a greater differentiation of the schooling system as indicated by streaming and a large share of private schools decreases educational opportunities while more instruction time increases educational opportunities. The empirical results that are based on a difference‐in‐differences estimation approach to control for country‐specific effects support these hypotheses.     

(Un)fair Delegation: Exploring the Strategic Use of Equity Rules in International Climate Negotiations

We provide a new approach for identifying a strategic use of equity arguments in international (climate) negotiations. We first develop a theoretical model of strategic delegation which accounts for both environmental as well as equity preferences. We show that the strategic use of equity arguments qualitatively depends on the extent to which environmental preferences can be misrepresented: representatives from different countries may be expected to have similar equity views rather than widely differing perceptions of a fair share. Based on survey data on climate negotiations, we then provide empirical evidence for differences between equity preferences of citizens from Germany, China, and the U.S. and the perceived view on the position of their respective countries.     

Sudden stops and output: an empirical Markov switching analysis

Sudden stops and their negative effects on GDP have recently received increased attention because quantitative easing has led to substantial capital inflows into emerging economies. We extend the empirical literature on the impact of sudden stops on GDP by proposing an alternative econometric approach which is multivariate, nonlinear and uses a novel way to identify sudden stops. We estimate a Markov switching vector autoregression with a latent variable indicating whether the economy is in a sudden stop regime. We use the maximum fraction of forecast error variance approach for partial structural identification of the vector autoregression model. Beyond confirming findings from the existing empirical literature on sudden stops, our results additionally show that (i) sudden stops are associated with regime switches (i.e., breaks in the behavior of economic variables), which have significantly negative and permanent effects on GDP; (ii) impulse responses to net capital inflow shocks are regime dependent with economies being more vulnerable to shocks during the sudden stop regime; and (iii) there were different main drivers of the output decline in historical sudden stop episodes.     

Casting light on energy efficiency: evidence on consumer inattention and imperfect information

We investigate consumer inattention and imperfect information regarding the financial benefits of energy-efficient lighting using a randomized controlled trial with 1084 observations. Results suggest that subjects generally know about cost savings of light-emitting diode (LED) bulbs – the central lighting technology of the future – but largely underestimate the magnitude of these savings. As a result, stated willingness-to-pay for an LED bulb increases on average by 2.53€ through the provision of information on expected lifetime costs. Additional evidence hints at further consumer confusion about attribute differences between lighting technologies.     

Monetary Policy, Agency Costs and Output Dynamics

This paper examines the role of financial market imperfections for output reactions to nominal interest rate shocks. Empirical evidence shows a hump-shaped impulse response function of output and suggests that credit supply co-moves with output. A monetary business cycle model with staggered price setting is presented where the firms' outlays for capital and labor must be covered by the sum of net worth of entrepreneurs and loans in the form of debt contracts. These properties are shown to generate a hump-shaped impulse response of output, which takes on the smooth and persistent appearance of the empirical output response when nominal wages are set in a staggered way, too.     

Climate Change and the Irreversibility Effect – Combining Expected Utility and MaxiMin

This paper analyzes decisions on emissions of a stock pollutant under uncertaintyin a two period model. Decisions are based on a weighted average of expected utility (EU) and the MaxiMin criterion. I first show that more weight on the worst case (less weight on EU) may lead to increased first period emissions. The effect of learning possibilities on emissions is not clear in general, but depends qualitatively on the weight given to MaxiMin: For the quadratic utility case, considering prospective learning increases today's abatement effort, i.e. the irreversibility effect holds, if the weight on EU is small. This contrasts standard results on the irreversibility effect for EU which translates to small weights on MaxiMin. There is, however, the possibility of a negative value of learning. It is shown that the irreversibility effect holds if and only if thevalue of learning is negative. Consequences for the applicability of generalized EU-MaxiMin are discussed.     

Fiscal federalism and the composition of public investment in Europe

We analyse the determinants of the composition of public investment in Europe, with a special focus on the role of fiscal decentralisation. The results suggest that fiscal decentralisation boosts economically productive public investment, notably infrastructure, and curbs the relative share of economically less productive investment, such as recreational facilities. While not readily reconcilable with the traditional theory of fiscal federalism, these findings can be interpreted in terms of the literature on fiscal competition, with not only tax rates but also the quality of public expenditure weighing in firms' location decisions.
