International patent analysis as a tool for corporate technology analysis and planning

New, techniques of international patent anabsis are illustrated and resultsfrom preliminary validity tests of these techniques are presented. Indicators of technological activity, technological significance and commercial potential are constructed, and used to analyze fiber-based opto-electronic couplers and monoclonal-antibody-based diagnostic kits at the levels o f the technology, nation and firm. The international patent indicators are found to be closely correlated with R&D expenditures, scientific publications and new product introductions. They also relate to these indicators in ways that moke sense as specified in simple regression models of the innovation process. Comparisons of patent analysis results with expert opinion (for two process technologies) reveal that technology–level analyzes conform quite well with expert opinion, but national – and firm–level analyes vary from a low to a modest correlation with expert opinion. The authors conclude that the techniques can provide important information for corporate technology management, but that studies of additional technologies and further validity tests are needed.     

The changing face of mainstream economics

This article argues that economics is currently undergoing a fundamental shift in its method, away from neoclassical economics and into something new. Although that something new has not been fully developed, it is beginning to take form and is centered on dynamics, recursive methods and complexity theory. The foundation of this change is coming from economists who are doing cutting edge work and influencing mainstream economics. These economists are defining and laying the theoretical groundwork for the fundamental shift that is occurring in the economics profession.     

Numeraire choice in normalized quadratic functional forms

A semi-nested test procedure is developed for choosing the numeraire for a normalized quadratic profit function when too few observations exist for nested hypothesis testing and when too many alternatives exis for conventional non-nested testing. Sensitivity of empirical results to choice of numeraire price is examined using agricultural data for the US and ten multistate regions. Few test conclusions vary by numeraire but own price input demand elasticities differ greatly.     

Testing the presence and the absence of purchasing power parity: results for fixed and flexible regimes

Recent empirical studies concerning purchasing power parity (PPP), using the concept of cointegraton, have tested the null hypothesis of the absence orthe presence of PPP. The disadvantage of using either of these approaches is that the conclusion is ambiguous when not rejecting the null: the result could be due to either the null hypothesis being true or by the low power of the test and lack of information in the data. Therefore, there is substantial information to be gained by applying both approaches within the same study. This study uses the ordinary DF test with PPP as the alternative hypothesis and a recently suggested test by Kwiatkowski et al. (1992) with PPP as the null. The tests are applied to four major industrial countries real exchange rates, each split into four different samples, including fixed as well as flexible exchange rate regimes. The absence of PPP cannot be rejected while the presence can be rejected.     

Measuring country event risk compensation on BRICs international portfolio management

The BRICs nations (Brazil, Russia, India and China) have a strong relative economic growth pattern in the world among economic powers. The allure of globalization has made the analysis and assessment of national critical component of international portfolio management in recent years. We construct the model from comparing the relative SD of stock return whereby higher SDs are generally associated with more risk. This relative SD forms a principle component in the change of the weights on the international portfolio choice. The result shows that event jump risk not only makes the investor's allocation more conservative overall, but also it can be compensated on BRICs event risk.     

Smokeless tobacco,smoking cessation and harm reduction: an economic analysis

Good estimates place ‘hard core’ smoking rates in the United States at approximately 25%, with little change over the decade of the 1990s. This paper examines the possibilities of ‘harm reduction’ with the use of smokeless tobacco. Specifically, using an econometric model we seek to determine whether an increase in the use of smokeless tobacco would lead to reduced smoking rates in the United States. Applying our model to the NHANES III (National Health and Nutrition Examination Survey) we find that the use of smokeless tobacco by an average U.S. male smoker would increase the average probability of smoke cessation by over 10%. Approximately 3 million additional ‘quits’ would result for 26 million smokers. Our study permits an examination of cessation by age groups and we find that males who use smokeless tobacco between 16 and 65 have a 10–14% probability of quitting but that the probability falls beyond age 66. Important implications for life extension and health costs would attend these results with, under conservative assumptions, life years saved approximating 2.16 million and health care cost-savings of about $3 billion per year.     

Source of income effects for demand decisions and taxable consumption

The relationship between sources of income and demand decisions by the household is examined here with an eye toward the ramifications on consumption tax bases. Income sources may be important when households attach psychic and transaction costs to individual purchases or when sources are assigned via a mental accounting process. In either case, general and specific sales tax bases may be affected by changes in income composition. Empirical results indicate two important findings. First, tax exemptions can introduce significant income source effects for a general consumption tax base. Second, the importance of differential tax rates for gasoline and food-at-home strongly depends on the mix of labour, capital, retirement and non-retirement transfer pay.     

Capacity utilization rates and unemployment rates: are they complements or substitutes in warning about future inflation?

This research examines capacity utilization as a measure of economic slack in the US economy. Many macroeconomists have questioned the use of capacity utilization as a measure of economics slack on several fronts. The first issue revolves around the definition and accuracy of measurement of the capacity utilization rate in the US economy. Since this research use existing Federal Reserve measures of capacity utilization no insights into the definition and measurement issues are offered other than the fact that a consistent role is found for two different Fed measures of capacity utilization in explaining inflation. The second issue effectively involves the concern as to robustness of the link between the capacity utilization rate and inflation. It was found that there is indeed reason for the Federal Reserve to take note of changes in capacity utilization when trying to determine its policy position with regard to inflation. Clearly, the high capacity measure developed in this research offers distinct information about the inflation process. The third issue raises the question as to whether the capacity utilization and unemployment rates are complements or substitutes in the inflation equation. Both rates tend to provide similar information regarding price changes at low levels of aggregate resource usage. However, as resource usage in the economy becomes increasingly close to its maximum potential, the labour market impact on inflation, as capture by unemployment rate measures, is distinctly different from that of capacity constraints. Finally, if the capacity utilization rate is indeed a useful measure of inflationary pressure, is there a threshold level of the capacity utilization rate above which policymakers should become particularly concerned about the potential of accelerating inflation? It was found that across two measures of inflation, the widely discussed capacity threshold level is in the 84-85% range.
