Deunionization in the US: a panel data analysis from 1973 to 1999

There are four different hypotheses analyzed in the literature that explain deunionization, namely: the decrease in the demand for union representation by the workers; the impaet of globalization over unionization rates; teehnieal ehange and ehanges in the legal and politieal systems against unions. This paper aims to test alI ofthem. We estimate a logistie regression using panel data proeedure with 35 industries from 1973 to 1999 and eonclude that the four hypotheses ean not be rejeeted by the data. We also use a varianee analysis deeomposition to study the impaet of these variables over the drop in unionization rates. In the model with no demographic variables the results show that these economic (tested) variables can account from 10% to 12% of the drop in unionization. However, when we include demographic variables these tested variables can account from 10% to 35% in the total variation of unionization rates. In this case the four hypotheses tested can explain up to 50% ofthe total drop in unionization rates explained by the model.

A comparison of test of non-linear cointegration with an application to the predictability of US interest rates using the term structure

We evaluate the forecasting performance of a number of systems models of US shortand long-term interest rates. Non-linearities, induding asymmetries in the adjustment to equilibrium, are shown to result in more accurate short horizon forecasts. We find that both long and short rates respond to disequilibria in the spread in certain circumstances, which would not be evident from linear representations or from single-equation analyses of the short-term interest rate.

The power of the purse : what do the data say on US federal budget allocation to the states?

This paper provides new evidence on the determinants of the allocation of the US federal budget to the states and tests the capability of congressional, electoral and partisan theories to explain such allocation. We find that socio-economic characteristics are important explanatory variables but are not sufficient to explain the disparities in the distribution of federal monies. First, prestige committee membership is not conducive to pork-barrelling. We do not find any evidence that marginal states receive more funding; on the opposite, safe states tend to be rewarded. Also, states that are historically "swing" in presidential elections tend to receive more funds. Finally, we find strong evidence supporting partisan theories of budget allocation. States whose governor has the same political affiliation of the President receive more federal funds; while states whose representatives belong to a majority opposing the president party receive less funds.

Why is patent production so comparatively low at Petrobras?

As a latecomer firm, Petrobras’ innovation progress has previously been measured in terms of its productive capacity, capability accumulation, and more recently in terms of its strategic R&D and new product development. Patents are an acceptable proxy for innovation, especially for complex innovations such as biofuels and deepwater oil exploration & production, and this study evaluates Petrobras’ patent intensity relative to Shell and ExxonMobil for the years 2008–2012. The study found that while Petrobras may be a world-leader in deepwater E&P, its patent activities and portfolio are not competitive with its peers. This low patent intensity (and, by proxy, innovation) of Petrobras’ is explained by past and present institutional, cultural, and firm-specific factors.

The Culture of entrepreneurship: a study of the entrepreneurial motivation and attitudes towards business creation in the UAE in comparison to the US and Brazil

This study demonstrates the cultural dimension and the surrounding environment of different entrepreneurs selected from three countries, the United States of America, the Federative Republic of Brazil, and the United Arab Emirates. The general objective is to understand the difference in the entrepreneurial motives and spirit towards venture creation from the three different countries. After conducting field research and collecting the required data, a deep analysis was conducted to draw a comparison between the three cultures from an individual’s point of view, to help shape a set of proposed recommendations, which could be used to improve the current culture of entrepreneurship in the UAE.
