Using a long dataset on openness and productivity this paper tests the influence of openness on TFP growth and per capita growth since 1870 for 16 industrialized countries. It is shown, in simple regressions, that growth is by and large independent of openness. However, once the interaction between openness and foreign knowledge is allowed for, productivity is positively affected by openness. J...

This paper considers a new-product firm’s choice between exporting and foreign direct investment (FDI) to access foreign markets. We find that, when quality is unknown to buyers, the firm may choose FDI over exporting to signal quality, even though FDI is a costlier mode of access than exporting. We then use the model to study the effect of local labor requirement policy imposed by the host cou...

The efficacy and toxicity of high-dose chemotherapy and autologous stem cell transplantation (HDCT/ASCT) were investigated for improving the outcomes of patients with relapsed medulloblastoma. A total of 15 patients with relapsed medulloblastoma were enrolled in the KSPNO-S-053 study from May 2005 to May 2007. All patients received approximately 4 cycles of salvage chemotherapy after relapse. T...

This paper proposes a new test of the Protection for Sale (PFS) model by Grossman and Helpman (1994). Unlike existing methods in the literature, our approach does not require any data on political organizations. We use quantile and quantile IV regressions to do so using the data from Gawande and Bandyopadhyay (2000). Surprisingly, the results do not provide any evidence favoring the PFS model. ...

The poverty mapping methodology for estimating welfare rankings from small areas has proven to be useful in guiding allocation of government funds, regional planning, and general policy formulation. Nevertheless, poverty mapping also suffers from a series of by now well recognized shortcomings. We apply an approach based on first order dominance (FOD) to small area estimation. Five advantages t...

[1] Precipitating particle data from the DMSP F12 and F13 satellites has been merged with image data from the Ultraviolet Imager (UVI) on the Polar satellite. UVI images were combined within single transpolar passes of the DMSP F12 and F13 satellites. Pixel irradiances were then averaged into 1 1 bins along the satellite tracks, thus generating along-track irradiance profiles. Similarly, energy...

Plasma probe data from DMSP-F13, DMSP-F15 and DEMETER satellites were used to examine longitudinal structures in the topside equatorial ionosphere during fall equinox conditions of 2004 year. Since the launch of DEMETER satellite on 29 June 2004, all these satellites operate close together in the topside ionosphere. Here, data taken from Special Sensor-Ion, Electron and Scintillations (SSIES) i...

To quantify trade frictions, we examine multiproduct exporters. We build a flexible general-equilibrium model and estimate market entry costs using Brazilian firm-product-destination data under rich demand access cost shocks. Our estimates show that additional products farther from firm’s core competency come at higher production costs, but there are substantive economies of scope in costs. Mar...
