Where is the entrepreneurship bang for the patenting buck? Utility versus design patents

This research contributes to the literature on entrepreneurship by studying whether design patents and utility patents have similar effects on entrepreneurial activity. Other contributions of this research include comparing the relative influences on startup versus established entrepreneurs and the effects of patents versus trademarks. Results, based on a panel of U.S. states, show that established entrepreneurs benefit from both types of patenting and from trademarks, whereas startup entrepreneurs significantly benefit from only design patents, and the effects of design patents and trademarks are opposite. These findings suggest that the entrepreneurship bang from the patenting buck might differ across patenting types.     

Unemployment and international shadow economy: gender differences

Adding to the body of research on cross-country determinants of the informal economy, this article studies how unemployment differences across gender drive the propensities to work in the informal sector. Results, accounting for possible simultaneity between unemployment and the shadow economy, show that unemployed males, rather than unemployed females, were more likely to operate underground. These findings about greater male propensities are generally robust to alternative considerations.     

Dynamics of U.S. State Cigarette Consumption: Evidence from Panel Error Correction Modeling

This study uses state-level data for nearly four decades to study the dynamic demand for cigarettes, focusing especially on the long-run equilibrium relationship between cigarette consumption and its determinants as well as the short-run and long-run causal dynamics. We find the presence of cointegration with the long-run equilibrium, indicating the price elasticity of cigarette demand to be negative and inelastic, the income elasticity is positive and the border smuggling effects are significant, with substantial variations across individual states. Of the various smoking control policies considered, questions remain as to the effectiveness of aggregate anti-smoking initiatives that treat all states alike. Furthermore, the causal dynamics reveal bi-directional causality between cigarette consumption and its determinants. Some policy implications are discussed.     

Obesity: An economic and financial perspective

Obesity has been slowly increasing in most countries. This problem has increased to an extent that it is being labeled an epidemic and a leading cause of preventable deaths, second only to smoking. This paper provides a synthesis of the extant economics literature on obesity. More importantly, a framework outlining the economic causes and effects of obesity is discussed. The causes of obesity are many, including economic, technical, historical, and biological. The effects of obesity can be external or internal. These effects, in turn, can be direct or indirect. Recommendations for governments and businesses and directions for future research are discussed. Helpful comments from James Payne and research assistance of Richard Connelly are appreciated. Financial support from the Katie School of Insurance at Illinois State University is gratefully acknowledged.     

Why Do Suppliers Charge Larger Buyers Lower Prices?

The phenomenon of input suppliers charging larger buyer firms, relative to smaller buyer firms, lower prices is commonly explained in terms of supplier economies of scale, supplier competition for larger buyers, and the larger bargaining power of larger buyers. This paper provides an alternative explanation, and shows that the observed direction of differential pricing can benefit the supplier by lowering the level of tacit collusion its buyers can sustain in their output market. This result also provides a new mechanism through which a ban on price discrimination by input suppliers may lower consumer welfare.     

R&D and Output in a Regulated Vertically Integrated Oligopoly

This paper examines input price regulation's effects on research and development (R&D) and output in a vertically integrated industry. A single integrated firm produces the crucial input and the output. The non-integrated rival does not produce the input but buys it from the integrated firm at a regulated price. Only the integrated firm engages in cost-reducing R&D. Results show that changes in input price have a negative effect on the integrated firm's output and R&D. The non-integrated firm's output response to changes in input price depends upon the slope of the demand curve. The welfare analysis examines the social desirability of such regulation.     

Productivity,energy prices and the great moderation: A new link

We build upon recent research that attributes the moderation of output volatility since the 1980s to the reduced volatility of the Total Factor Productivity (TFP) by investigating the linkage between energy price fluctuations and the stochastic process for TFP. First, we estimate a joint stochastic process for the energy price and TFP and establish that until around 1982, energy prices negatively affected TFP. This spillover has since disappeared. Second, we show that within the framework of a Dynamic Stochastic General Equilibrium (DSGE) model, the disappearance of this energy-productivity spillover accounts for close to 68 percent of the moderation in output volatility.     

The nexus of white collar crimes: shadow economy,corruption and uninsured motorists

This article empirically examines the nexus of three white collar crimes: shadow economy, corruption and uninsured motorists. Whereas the shadow economy–corruption linkage has been studied, the linkages with uninsured motorists have not been formally studied. Results, based on US data and accounting for possible bidirectional causalities, show complementarity between shadow economy and corruption and between uninsured motorists and the shadow economy. The magnitude of the impact of uninsured motorists on the shadow economy is greater than that of corruption. In other findings, shadow economy was lower in most prosperous states and in states that did not impose a sales tax.     

The internet as an indicator of corruption awareness

We apply a standard specification of the causes of corruption to a large sample of countries to investigate the effect of internet awareness about corruption on prevalence and perceptions of corruption. The main hypothesis is that greater corruption awareness acts as a corruption deterrent. A unique data set of internet searches on Google and Yahoo is compiled using alternate variations of “corruption”, “bribery” and “country name” keywords to capture internet corruption awareness. Results show that internet hits about corruption per capita correlate negatively with corruption perceptions and corruption incidence. This finding generally holds for different specifications and other robustness checks.
