The German start-up subsidy (SUS) program for the unemployed has recently undergone a major makeover, altering its institutional setup, adding an additional layer of selection and leading to ambiguous predictions of the program's effectiveness. Using propensity score matching (PSM) as our main empirical approach, we provide estimates of long-term effects of the post-reform subsidy on individual employment prospects and labor market earnings up to 40 months after entering the program. Our results suggest large and persistent long-term effects of the subsidy on employment probabilities and net earned income. These effects are larger than what was estimated for the pre-reform program. Extensive sensitivity analyses within the standard PSM framework reveal that the results are robust to different choices regarding the implementation of the weighting procedure and also with respect to deviations from the conditional independence assumption. As a further assessment of the results' sensitivity, we go beyond the standard selection-on-observables approach and employ an instrumental variable setup using regional variation in the likelihood of receiving treatment. Here, we exploit the fact that the reform increased the discretionary power of local employment agencies in allocating active labor market policy funds, allowing us to obtain a measure of local preferences for SUS as the program of choice. The results based on this approach give rise to similar estimates. Thus, our results indicating that SUS are still an effective active labor market program after the reform do not appear to be driven by "hidden bias."
Is trade a promoter of peace? Adam Smith, one of the earliest defenders of trade, worries that commerce may instigate some perverse incentives, encouraging wars. The wealth that commerce generates decreases the relative cost of wars, increases the ability to finance wars through debts, which decreases their perceived cost, and increases the willingness of commercial interests to use wars to extend their markets, increasing the number and prolonging the length of wars. Smith, therefore, cannot assume that trade would yield a peaceful world. While defending and promoting trade, Smith warns us not to take peace for granted.
This paper studies the effects of two different frames on decisions in a dictator game. Before making their allocation decision, dictators read a short text. Depending on the treatment, the text either emphasizes their decision power and freedom of choice or it stresses their responsibility for the receiver’s payoff. Including a control treatment without such a text, three treatments are conducted with a total of 207 dictators. Our results show a different reaction to these texts depending on the dictator’s gender. We find that only men react positively to a text that stresses their responsibility for the receiver, while only women seem to react positively to a text that emphasizes their decision power and freedom of choice.
This paper presents an experiment on the effect of retroactive price-reduction schemes on buyers’ repeated purchase decisions. Such schemes promise buyers a reduced price for all units that are bought in a certain time frame if the total quantity that is purchased passes a given threshold. This study finds a loyalty-enhancing effect of retroactive price-reduction schemes only if the buyers ex-ante expected that entering into the scheme would maximize their monetary gain, but later learn that they should leave the scheme. Furthermore, the effect crucially hinges on the framing of the price reduction.
Spatial and social mobility
(2018)
This paper analyzes the relationship between spatial mobility and social mobility. It develops a two-skill-type spatial equilibrium model of two regions with location preferences where each region consists of an urban area that is home to workplaces and residences and an exclusively residential suburban area. The paper demonstrates that relative regional social mobility is negatively correlated with segregation and inequality. In the model, segregation, income inequality, and social mobility are driven by differences between urban and residential areas in commuting cost differences between high-skilled and low-skilled workers, and also by the magnitude of taste heterogeneity.
This paper tests the robustness of voluntary cooperation in a sequential best shot game, a public good game in which the maximal contribution determines the level of public good provision. Thus, efficiency enhancing voluntary cooperation requires asymmetric behavior whose coordination is more difficult. Nevertheless, we find robust cooperation irrespective of treatment-specific institutional obstacles. To explain this finding, we distinguish three behavioral patterns aiming at both, voluntary cooperation and (immediate) payoff equality.
This paper presents results from an experiment on the effects of recommended retail prices on consumer and retailer behaviour. We present evidence that recommended retail prices, despite their non-binding nature, influence consumers’ willingness to pay by setting a reference point. At a given price, consumers buy more the higher the recommended retail price is, and their demand drops at prices above the recommended retail price, even when it is entirely uninformative about the value of the product. Retailers in this study are subject to similar anchoring effects, but they do not anticipate consumers’ behaviour well and are thus not able to exploit their behavioural biases.
The Rise of Populism
(2017)
Drawing on the recent political developments in Europe and the USA, and the public discourse since 2016, an analysis of the rise of populism on the left and the right is articulated with the aim to provide an understanding of the contemporary populist political landscape. The Trump phenomenon and his form of populism is analysed within the context of foreign policy and development aid. This is contrasted with the neoliberal view couched in Fukuyama’s ‘End of History’ theorem, and the current popular sentiment towards anti-establishment and anti-globalisation in Western democracies.
Growing out of the crisis
(2013)
Greece’s currently planned institutional reforms will help to get the country going with limited economic growth. With an economy based primarily on tourism, trade, and agriculture, Greece lacks an established competitive industry and an innovation-friendly environment, resulting in a low export ratio given the small size of the country and its long-time EU-membership. Instead, Greece exports only its nation's talent, with low returns. To become prosperous, the country must better capitalize on its Eurozone membership and add innovative sectors to its economic structure. Given Greece's hidden assets, such as the attractiveness of the country, a small number of strong research centers and an impressive diaspora in research, finance and business, we envision a Greek “Silicon Valley” and propose a ten point policy plan to achieve that goal.
