Adverse Selection And Incentives In An Early Retirement Program, Kenneth T. Whelan, Ronald G. Ehrenberg, Kevin F. Hallock, Ronald L. Seeber Jan 2013

Adverse Selection And Incentives In An Early Retirement Program, Kenneth T. Whelan, Ronald G. Ehrenberg, Kevin F. Hallock, Ronald L. Seeber

Ronald G. Ehrenberg

We evaluate potential determinants of enrollment in an early retirement incentive program for non-tenure-track employees of a large university. Using administrative record on the eligible population of employees not covered by collective bargaining agreements, historical employee count and layoff data by budget units, and public information on unit budgets, we find dips in per-employee finance in a budget unit during the application year and higher recent per employee layoffs were associated with increased probabilities of eligible employee program enrollment. Our results also suggest, on average, that employees whose salaries are lower than we would predict given their personal characteristics and …


Export Decisions Of Services Firms Between Agglomeration Effects And Market-Entry Costs, Henk Lm Kox Apr 2012

Export Decisions Of Services Firms Between Agglomeration Effects And Market-Entry Costs, Henk Lm Kox

Henk LM Kox

The paper tests the role of agglomeration effects on the export decision of services firms. Recent theories on trade with heterogeneous firms predict that export participation goes along with sunk market-entry costs. Only the more productive firms will be able to overcome these sunk costs. This leads to a process of - ex ante - self selection. These predictions are tested for the services industry, with due account for the possible role of agglomeration effects in large-city areas. Standard empirical tests of the new trade models consistently find productivity-based ex ante self selection by exporters, and this effect is mostly …


Impacts Of Formal Financing On The Development Of The Sudanese Agricultural Sector, Issam A.W. Mohamed Professor Aug 2011

Impacts Of Formal Financing On The Development Of The Sudanese Agricultural Sector, Issam A.W. Mohamed Professor

Professor Issam A.W. Mohamed

The agricultural sector of Sudan is faced by many problems. In the irrigated schemes, the government who officially owns most of them there are entrenched managerial problems that brewed for more than six decades. Moreover, the privatization policies of those schemes provoked many outcries and protests. Large schemes like Gezira have collapsed, this year 2011, only 10% of its over one million hectares were cultivated. The rainfed farming is not different with lack of machineries, shortages of available labor and high priced agricultural inputs, it is not expected to fare better than the irrigated schemes. However, even if those problems …


Exports And Productivity Selection Effects For Dutch Firms, Henk Lm Kox, Hugo Rojas Romogosa Dec 2009

Exports And Productivity Selection Effects For Dutch Firms, Henk Lm Kox, Hugo Rojas Romogosa

Henk LM Kox

The paper tests whether recent theories of international trade with heterogeneous firms can explain the export patterns in Dutch firm- and plant- level data in manufacturing and services. Recent trade models with heterogeneous firms predict that the export decision of firms is affected by sunk entry costs in foreign markets, with only the most productive firms self-selecting into exports. We test a latent variable model of the export decision by probit regressions and standard OLS panel regressions. Our results support the self-selection prediction. The process further appears to be conditioned by scale effects, market structure and multinational affiliation. Regarding alternative …
