Do Patent Protection and Technology Transfer Facilitate R&D in Developed and Emerging Countries? A Semiparametric Study

This paper examines if patent protection and technology transfer facilitate R&D in a sample that includes both developed and emerging countries. A semiparametric model is used to estimate the relevant parameters using country level data from 21 countries, of which six are emerging, for the period 1981–1997. The results suggest thresholds in patent protection and technology transfer: patent protection has a positive effect which weakens at high levels of protection, and FDI has a positive effect only if the country depends heavily on FDI.

Are there racial differences in faculty salaries?

Many studies have used micro-level data in estimating earnings differentials by gender for college professors. None has studied racial earnings differences for faculty except by employing a dummy variable for race in its regression models. The availability of the 1993 National Study of Postsecondary Faculty has made such a study possible. We use a variant of the Oaxaca decomposition technique suggested by Cotton (1988) and Neumark (1988). Although the salaries of black faculty trail those of their white counterparts at the Associate and Full Professor levels, the reverse is true at the Assistant Professor level. The increased emphasis in recent years on increasing diversification in the racial composition of college faculty are possible explanations.

Finding Missing Markets (and a Disturbing Epilogue): Evidence from an Export Crop Adoption and Marketing Intervention in Kenya

Farmers may grow crops for local consumption despite more profitable export options. DrumNet, a Kenyan NGO that helps small farmers adopt and market export crops, conducted a randomized trial to evaluate its impact. DrumNet services increased production of export crops and lowered marketing costs, leading to a 32% income gain for new adopters. The services collapsed one year later when the exporter stopped buying from DrumNet because farmers could not meet new EU production requirements. Farmers sold to other middlemen and defaulted on their loans from DrumNet. Such experiences may explain why farmers are less likely to adopt export crops.     

The Effects of Greenfield FDI and Cross‐border M&As on Total Factor Productivity

We examine the effects of greenfield FDI and cross‐border mergers and acquisitions (M&As) on total factor productivity (TFP) in developed and developing host countries of FDI. Using panel data for up to 123 countries over the period from 2003 to 2011, we find that greenfield FDI has no statistically significant effect on TFP, while M&As have a positive effect on TFP in the total sample. Greenfield FDI and M&As both appear to be ineffective in increasing TFP in the subsample of developing countries. In contrast, M&As have a strong and positive effect on TFP in the subsample of developed countries.     

Scraping EDGAR with Python

This article presents Python codes that can be used to extract data from Securities and Exchange Commission (SEC) filings. The Python program web crawls to obtain URL paths for company filings of required reports, such as Form 10-K. The program then performs a textual analysis and counts the number of occurrences of words in the filing that reflect, for example, uncertainty (or any other quality specified by the researcher). The program can be easily modified to conduct other searches by changing the word list, company names, or SEC filings. The Python program could be used in an introductory graduate data analytics course in finance that has a web crawling or textual analysis component.
