Saddlepoint approximations for the doubly noncentral t distribution

Closed-form approximations for the density and cumulative distribution function of the doubly noncentral t distribution are developed based on saddlepoint methods. They exhibit remarkable accuracy throughout the entire support of the distribution and are vastly superior to existing approximations. An application in finance is considered which capitalizes on the enormous increase in...

Democratic public good provision

Expenditures are financed through age-dependent taxation that distorts human capital investment. Taxes redistribute income both across skill groups and across generations. We focus on politico-economic Markov equilibria and contrast these with the Ramsey allocation...

Does risk equalization reduce the viability of voluntary deductibles?

Theoretically, a risk avers consumer takes a deductible if the premium rebate (far) exceeds his/her expected out-of-pocket expenditures. In the absence of risk equalization, insurers are able to offer high rebates because those who select into a deductible plan have below-average expenses. This paper shows that, for high deductibles, such rebates cannot be offered if risk...

To address this issue, we study a microstructure model in which a commercial...

Count Data Models with Unobserved Heterogeneity: An Empirical Likelihood Approach

As previously argued, the correlation between included and omitted regressors generally causes inconsistency of standard estimators for count data models. Using a specific residual function and suitable instruments, a consistent generalized method of moments estimator can be obtained under conditional moment restrictions. This approach is extended here by fully exploiting the model...

Time Horizon, Costs of Equity Capital and Generic Investment Strategies of Firms

Recent literature (McNulty, Yeh, Schulze, & Lubatkin, 2002) states that the assumptions behind the capital asset pricing model, in particular the irrelevance of time horizon, do not correspond to the characteristics of firms that prefer long-term investment horizons. I show that family firms display a longer time horizon than most of their nonfamily counterparts, since (1) family...

Analyzing economic market interactions as conflicts: new concepts to assess market-based policy instruments

Complementing market-based policy instruments with conflict analysis approaches provides a wider understanding of market situations and allows to identify minimal requirements regarding needs, power and conflict dynamics. If these are not met, a market cannot be successfully introduced or a liberalization process implemented. Conflict analysis offers a language better suited to the...
