Reassessing the productivity gains from trade liberalization

This paper reassesses the impact of trade liberalization on productivity. We build a new, unique database of effective tariff rates at the country‐industry level for a broad range of countries over the past two decades. We then explore both the direct effect of liberalization in the sector considered, as well as its indirect impact in downstream industries via input linkages. Our findings point to a dominant role of the indirect input market channel in fostering productivity gains. A 1 percentage point decline in input tariffs is estimated to increase total factor productivity by about 2 percent in the sector considered. For advanced economies, the implied potential productivity gains from fully eliminating remaining tariffs are estimated at around 1 percent, on average, which do not factor in the presumably larger gains from removing existing non‐tariff barriers. Finally, we find suggestive evidence of complementarities between trade and FDI liberalization in boosting productivity. This calls for a broad liberalization agenda that cuts across different areas.     

Strategic Environmental Policy and International Trade in Asymmetric Oligopoly Markets

This paper examines optimal cooperative and non-cooperative environmental taxes for the case in which a polluting input is used to produce an internationally-traded finished product. The model allows for terms-of-trade effects under oligopoly and employs a general specification of the environmental damage function that encompasses special cases of local, global, and transboundary externalities. The model has several implications for public finance. For example, inefficiently high environmental taxes may be optimal for a net exporting country in non-cooperative circumstances, as the motive to shift rent by selecting an inefficiently low tax rate is countervailed by the incentive to shift the burden of the tax to foreign consumers. The findings identify the important role of asymmetric trade flows (denominated in both goods and pollution exchange) in determining optimal cooperative and non-cooperative tax policy under oligopoly.     

Cross‐National Analysis of Gender Differences in Job Satisfaction

Research over the past two decades has found significant gender differences in subjective job satisfaction, with the result that women report greater satisfaction than men in some countries. This paper examines the so‐called “gender paradox” using data from the European Social Survey for a subset of fourteen countries in the European Union. We focus on the hypothesis that women place higher values on certain work characteristics than men, which explains the observed differential. Using estimates from Probit and ordered Probit models, we conduct standard Blinder–Oaxaca decompositions to estimate the impact that differential valuations of characteristics have on the gender difference in self‐reported job satisfaction. The results indicate that females continue to report higher levels of job satisfaction than do men in some countries, and the difference remains even after controlling for a wide range of personal and job characteristics and working conditions. The decompositions suggest that a relatively small share of the gender differential is attributable to gender differences in the weights placed on working conditions in most countries. Rather, gender differences in job characteristics contribute relatively more to explaining the gender–job satisfaction differential.     

“I even met happy gypsies”

Economic studies of the Roma population, which is the largest and the poorest ethnic minority in Europe, remain sparse due to the limited availability of appropriate micro level data. This paper provides a comparative analysis of life satisfaction between Roma and non‐Roma young adults aged between 15 and 24 years using survey data collected from Serbia in 2010 and from Bosnia and Herzegovina in 2011. Results from raw answers show that the young Roma population living in settlements is less satisfied with life than non‐Roma. However, we find instead that the former group is more satisfied once we account for the fact that Roma have more disadvantaged characteristics on average. Also, Roma young adults expect a better life within one year compared to the non‐Roma in Serbia while there is no difference in Bosnia and Herzegovina.     

Can Reform Waves Turn the Tide? Some Case Studies using the Synthetic Control Method

A number of advanced economies carried out a sequence of extensive reforms of their labor and product markets in the 1990s and early 2000s. Using the Synthetic Control Method (SCM), this paper implements six case studies of well-known waves of reforms, those of New Zealand, Australia, Denmark, Ireland and Netherlands in the 1990s, and the labor market reforms in Germany in the early 2000s. In four of the six cases, GDP per capita was higher than in the control group as a result of the reforms. No difference between the treated country and its synthetic counterpart could be found in the cases of Denmark and New Zealand, which in the latter case may have partly reflected the implementation of reforms under particularly weak macroeconomic conditions. Overall, also factoring in the limitations of the SCM in this context, the results are suggestive of a positive but heterogenous effect of reform waves on GDP per capita.     

Nonparametric density estimation in compound Poisson processes using convolution power estimators

Consider a compound Poisson process which is discretely observed with sampling interval $\Delta $ until exactly $n$ nonzero increments are obtained. The jump density and the intensity of the Poisson process are unknown. In this paper, we build and study parametric estimators of appropriate functions of the intensity, and an adaptive nonparametric estimator of the jump size density. The latter estimation method relies on nonparametric estimators of $m$ th convolution powers density. The $L^2$ -risk of the adaptive estimator achieves the optimal rate in the minimax sense over Sobolev balls. Numerical simulation results on various jump densities enlight the good performances of the proposed estimator.     

Rock art tourism in the uKhahlamba/Drakensberg World Heritage Site: obstacles to the development of sustainable tourism

This paper focuses on rock art tourism, a highly vulnerable heritage of broad public interest, only sustainable within an effective management framework. The paper explores tourism management in South Africa's uKhahlamba-Drakensberg World Heritage Site, inscribed in 2000 for its natural landscapes and its exceptional rock art heritage. In practice, nature dominates the area's tourism and management dynamics. Current tourism patterns, markets and frequencies, together with rock art's low place within tourist agendas, are described. This situation is shown to be a legacy of European Alpine romanticism, and the political rejection of indigenous cultural heritage prior to 1994, still expressed through visitor patterns and marketing policies. Despite rock art needing tourism to valorise its conservation, and being recognised by commentators and the state as a viable route to tourism development, heritage conservation, socio-economic regeneration and cultural empowerment, the failure to reform entrenched and ineffective tourism/conservation governance and management systems is exposed. The problems affecting rock art tourism have allowed the retention of unwelcome values from South Africa's pre-democratic era, risk the loss of World Heritage site status, the destruction of globally outstanding art works and waste an important opportunity to expand and diversify sustainable tourism in South Africa.
