Embeddedness of innovation receivers in the multinational corporation: Effects on business performance

This paper investigates how relationship embeddedness in MNC subsidiaries’ corporate and external networks influences the contribution of innovation transfer to the recipient subsidiary's business performance. OLS regressions using data on the intra-MNC transfer of 224 innovations indicate that the embeddedness of a subsidiary's relationships in the corporate and external network positively affects the received innovation's contribution to business performance. More detailed analysis demonstrates that the positive link between a subsidiary's embeddedness in the external network and the contribution to business performance of receiving an innovation is negatively affected when the innovation is unique compared with other innovations on the market.     

Revisiting the democracy-private investment nexus: Does inequality matter?

Contrary to the predictions of a large theoretical literature, recent cross-country evidence suggests autocracies can generate statistically indistinguishable levels of private investment compared to democracies. We argue that the previous exclusion of inequality explains part of this puzzle. We model current investment as a function of investors’ beliefs about future tax rates, which are conditioned by the constraints on the Executive in setting tax rates and expropriating tax revenues. In democracies, where tax rates reflect the preferences of the median voter, investment declines with rising inequality. In autocracies, investor beliefs about future tax rates reflect the relative power of Elites compared to the Executive. As inequality rises, the increased resources available to Elites constrains the Executive’s ability to expropriate more tax revenues. The heterogeneous determinants of investor beliefs can explain the observed pattern of investment across regime types. We first test our predictions at the macro-level with cross-country data. We then test the behavioral underpinnings of our model with a novel laboratory experiment showing how inequality affects individual-level investment behavior dependent upon regime type. Results from both types of analyses show that when inequality is taken into account autocracies can generate similar levels of investment to democracies.     

On <Emphasis Type=Italic>q</Emphasis>-optimal martingale measures in exponential Lévy models

We give a sufficient condition to identify the q-optimal signed and the q-optimal absolutely continuous martingale measures in exponential Lévy models. As a consequence, we find that in the one-dimensional case, the q-optimal equivalent martingale measures may exist only if the tails for upward jumps are extraordinarily light. Moreover, we derive the convergence of q-optimal signed, resp. absolutely continuous, martingale measures to the minimal entropy martingale measure as q approaches one. Finally, some implications for portfolio optimization are discussed. C.N. gratefully acknowledges financial support by UniCredit, Markets and Investment Banking.

Targeting Teaching: Does the Medium Matter? Online versus Paper Coursework

If individuals process information differently when it is accessed electronically rather than on paper, then the transition from paper to electronic text may affect learning and retention. Using a randomized experiment, we compare learning outcomes of economics students who use electronic teaching tools with students who access the same material on paper. We find that students who submit homework online complete more assignments but have lower classroom attendance rates. However, there is no effect on exam scores. This suggests that while an electronic medium may enable instructional material to be accessed more easily, it does not significantly impact learning.     

Examining the carbon emission impact of livelihood transitions in pro-poor tourism

This study examines carbon dioxide (CO₂) emission changes from livelihood transitions during tourism development to assess the environmental impact of pro-poor tourism (PPT) in China. The results indicate that livelihood transitions during PPT increased household income but also produced more CO₂ emissions. CO₂ emissions vary depending on factors including livelihood types after transition, income and household sizes, etc. The CO₂ per unit of income from tourism-based livelihoods is higher than from non-tourism-based livelihoods. Different livelihood strategies post transition also affect emissions. Practical suggestions that may mitigate emissions while not compromising residents’ income levels are provided.
