Comparing Conventional and New Policy Approaches for Carnivore Conservation: Theoretical Results and Application to Tiger Conservation

New policy approaches to facilitate the co-existence of wildlife and livestock are needed for situations where predation incidents greatly impact households’ income and retaliatory killing threatens endangered carnivore species’ survival. In this paper, models are developed to assess how two alternative policy approaches impact a herder’s decisions on carnivore hunting and livestock protection. We find that while the well-established ex-post compensation policy induces suboptimal livestock protection it can generate sufficient incentives for the herder to refrain from hunting so that the carnivore population reaches its socially optimal level. Performance payments are proposed as alternative policy. They are found not to distort livestock protection incentives and can also help achieve a socially optimal carnivore population level. Which of the two scheme types gives rise to less cost is ambiguous. An empirical analysis of the model with data from tiger-livestock conflicts in India is presented.     

International trade in durable goods: Understanding volatility, cyclicality, and elasticities

Data for OECD countries document: 1. imports and exports are about three times as volatile as GDP; 2. imports and exports are pro-cyclical, and positively correlated with each other; 3. net exports are counter-cyclical. Standard models fail to replicate the behavior of imports and exports, though they can match net exports relatively well. Inspired by the fact that a large fraction of international trade is in durable goods, we propose a two-country two-sector model in which durable goods are traded across countries. Our model can match the business cycle statistics on the volatility and comovement of the imports and exports relatively well. The model is able to match many dimensions of the data, which suggests that trade in durable goods may be an important element in open-economy macro models.     

The Roles of Performance Measures and Monitoring in Annual Governance Decisions in Entrepreneurial Firms

This paper analyzes annual corporate governance decisions at firms making initial public offerings (IPOs) of common stock between 1996 and 1999. Our objective is to examine relations between firms' corporate governance decisions and the informativeness of available measures of managerial performance. We consider financial measures such as earnings and stock return, as well as direct monitoring. We collect a sample of IPO firms from the manufacturing, Internet, and technology (non-Internet) industries, and examine how the use of various performance measures in annual compensation grants and turnover decisions varies with the information environment of the firm and with the extent of venture capital influence. Consistent with prior research that finds earnings are of limited usefulness in firm valuation for Internet firms, we find Internet firms place less importance on earnings and greater importance on stock returns in determining compensation grants than do non-Internet firms. We also find that compensation grants of firms with little or no venture capital influence display significantly stronger association with accounting and stock performance measures than those of firms with more intense monitoring by venture capitalists. This result is consistent with direct monitoring and the use of explicit performance measures acting as substitute governance mechanisms.

Optimal designs for models with block-block resp. treatment-treatment correlations

Summary In this paper we study optimal designs assuming two special covariance structures of the observations, namely that the covariance between the observations depends only on the blocks resp. the treatments. We show that the weighted least squares estimator equals the ordinary least squares estimator. Then we prove that block-block correlations resp. treatment-treatment correlations do not have any influence on the A- and MV-optimality resp. A-optimality. For the study of the MV-optimality in the case of treatment-treatment correlations we use the idea of invariance to find optimal C-matrices.     

Staatsverschuldung: Privilegien des Staates auf dem Prüfstand

Even though governments usually enjoy favourable borrowing conditions, the current financial system in Europe grants special privileges to government debt. This involves capital requirements in banking regulation, ECB policies, intergovernmental guarantees, etc. The paper gives a short outline of the privileges, discusses their justification and highlights problems.     

Fracking in Deutschland — eine Option für die Zukunft!

Extraction of shale gas in Germany (fracking) is better left as an option for the future. Today, owners of deposits in many other countries have uncertain property rights and extract too quickly. German deposits may appreciate in value if left in the ground. They also better contribute to national energy security there than if extracted and depleted. Waiting also allows Germany to learn from the mistakes of others and to take this new information and the improvements in extraction technology into account when deciding about extraction in the future. Such decisions should not be left to the resource extraction industries. Their objectives are likely to differ from the objective of maximising the rent from the nation’s shale gas.     

Fighting multiple tax havens

This paper develops a competition theory framework that evaluates an important aspect of the OECD's Harmful Tax Practices Initiative against tax havens. We show that the sequential nature of the process is harmful and more costly than a “big bang” multilateral agreement. The sequentiality may even prevent the process from being completed successfully. Closing down a subset of tax havens reduces competition among the havens that remain active. This makes their “tax haven business” more profitable and shifts a larger share of rents to these remaining tax havens, making them more reluctant to give up their “tax haven business”. Moreover, the outcome of this process, reducing the number of tax havens, but not eliminating them altogether, may reduce welfare in the OECD.     

The lifeboat problem

We study an all-pay contest with multiple identical prizes (“lifeboat seats”). Prizes are partitioned into subsets of prizes (“lifeboats”). Players play a two-stage game. First, each player chooses an element of the partition (“a lifeboat”). Then each player competes for a prize in the subset chosen (“a seat”). We characterize and compare the subgame perfect equilibria in which all players employ pure strategies or all players play identical mixed strategies in the first stage. The partitioning of prizes can lead to coordination failure when players employ nondegenerate mixed strategies. In these equilibria some rents are sheltered and rent dissipation is reduced.
