Entry, Exit and Productivity: Empirical Results for German Manufacturing Industries Using panel data from Spain Farinas and Ruano (IJIO 2005) test three hypotheses from a model by Hopenhayn (Econometrica 1992): (H1) Firms that exit in year t were in t-1 less productive than firms that continue to produce in t. (H2) Firms that enter in year t are less productive than incumbent firms in year t. (...
T study develops and estimates a model to empirically identify two behavioral effects (namely consumption flexibility and state dependence) that may underlie temporal and horizontal assortment choice, using scanner panel data where consumption information is unavailable. The proposed approach permits a consumer’s consumption utility to be dependent on previous consumptions, thus capturing state...

In this paper the heterogeneous firms and trade literature is extended by integrating quality of inputs and outputs in a food and agricultural setting, along with an analysis of how the ability to translate capability into higher product quality is critical in evaluating the cut-offs for food processing firms to enter domestic and export markets. Specifically, it is found that the direction of ...

Using panel data for a maximum of 109 countries over the years 1976-2000, we empirically analyze the impact of decentralization on the occurrence of transnational terror. Our results show that expenditure decentralization robustly reduces the number of terror events in a country, while political decentralization has no impact. The effects of decentralization do not transmit through government e...
Microfinance supports mainly informal activities that often have a low return and low market demand. It may therefore be hypothesized that the aggregate poverty impact of microfinance is modest or even nonexistent. If true, the poverty impact of microfinance observed at the participant level represents either income redistribution or short-run income generation from the microfinance interventio...
Two designs of a microscale electron ionization EI source are analyzed herein: a 3-panel design and a 4-panel design. Devices were fabricated using microelectromechanical systems technology. Field emission from carbon nanotube provided the electrons for the EI source. Ion currents were measured for helium, nitrogen, and xenon at pressures ranging from 10−4 to 0.1 Torr. A comparison of the perfo...
The acoustic performance of passive or active panel structures is usually tested in sound transmission loss facilities. A reverberant sending room, equipped with one or a number of independent sound sources, is used to generate a diffuse sound field excitation which acts as a disturbance source on the structure under investigation. The spatial correlation and coherence of such a synthesized non...
BACKGROUND In the absence of a gold standard, a panel of experts can be invited to assign a reference diagnosis for use in research. Available literature offers limited guidance on assembling and working with an expert panel for this purpose. We aimed to develop a protocol for an expert panel consensus diagnosis and evaluated its applicability in a pilot project. METHODS An adjusted Delphi me...
