Does the ban on trans-fats improve public health? In search of the optimal policy response

This paper examines the contribution of the regulatory ban on trans-fats and voluntary trans-fat regulation to public health outcomes for a sample of 39 countries in the period 1990–2015. To this end, we exploit within-country variation in trans-fat legislation to estimate the impact of the trans fat ban on cardiovascular mortality and obesity rates. Our difference-in-difference estimates indicate modest and beneficial effects of the trans-fats ban in reducing cardiovascular mortality and obesity rate. We find that the ban on trans fats tends to decrease the mortality rate attributed to cardiovascular diseases while the effects on the obesity rates are significant, especially among children and adolescent age group. By contrast, voluntary regulation of trans fats and demand-driven regulatory strategies are generally not associated with a marked drop in the obesity rate. By controlling for country-specific time trends, we show that the estimated mortality- and obesity-related impact of the ban is not driven by pre-existing trends, and does not affect non-cardiovascular mortality rate.

     

Endogenous economic freedom and the wealth of nations: evidence from a panel of countries, 1996–2011

Indexes of economic freedom measure the degree to which the policies and institutions of countries are supportive of economic freedom. The authors find a considerable scope for improvement in Index of Economic Freedom, created by Heritage Foundation, since not all components of index have equal effect on economic well-being. Contrary to Heritage methodology the authors tackle the aggregation bias and highlight that each index component contributes differently to the level of economic freedom and subsequently to the level of income per capita. The level of fiscal freedom and monetary freedom exert the strongest influence on the overall index of economic freedom. Authors present the new endogenous cross-country ranking of 135 countries from Instrumental Variable-Two Stage Least Squares (IV-2SLS) empirical specification which removes the inconsistencies arising from the arbitrary assumption of the equivalent effect of each component on the overall index and, hence, the level of real income per capita.     

Quality shock vs. market shock: Lessons from recently established rapidly growing U.S. startups

The 2003 Fortune 500 Index includes 358 firms that had been newly listed within the previous 10 years; historically this is a large number of firms in a relatively short time period. In particular, among the 358 new Fortune 500 entrants founded after 1975, 44 are defined as “rapid-growth” startups. Simulation results based on a discrete-choice racing model demonstrate that they were able to outperform their early competitors through a quality innovation race. They were resistant to hostile M&A attempts as well. According to the empirical results, a quality shock affects the size growth and profitability of the rapid-growth startups more than a market shock does, which indicates that such superior performance owes to firm-specific innovation ability rather than to market fluctuations.     

Transaction costs and economic growth under common legal system: State‐level evidence from Mexico

This paper examines the contribution of administrative and procedural transaction costs to economic growth under common legal system. We show that administrative and procedural costs vary quite a lot even within the institutional environment sharing the common legal system. States with low‐cost business registration, low‐cost access to property rights and greater judicial efficiency tend to have consistently higher growth. The established effects are robust to alternative model specifications, heterogeneity bias, and to a variety of control variables that might confound the effects of administrative and procedural costs on growth. Such differences in costs are far from being trivial as we show that these within‐system differences might be instrumental in influencing economic growth. Lower administrative and procedural costs induce growth by increasing investment rate, lowering unemployment rate, encouraging labor supply and improving total factor productivity. In the counterfactual scenario, the transition from high‐cost to low‐cost regime is associated with substantial growth and development gains over time. By exploiting the variation in the disease environment, ethnic fractionalization and historical urbanization, we show that the negative effect of rising procedural and administrative costs on growth and development appears to be causal.     

Mean squared error of ridge estimators in logistic regression

It is well known that the maximum likelihood estimator (MLE) is inadmissible when estimating the multidimensional Gaussian location parameter. We show that the verdict is much more subtle for the binary location parameter. We consider this problem in a regression framework by considering a ridge logistic regression (RR) with three alternative ways of shrinking the estimates of the event probabilities. While it is shown that all three variants reduce the mean squared error (MSE) of the MLE, there is at the same time, for every amount of shrinkage, a true value of the location parameter for which we are overshrinking, thus implying the minimaxity of the MLE in this family of estimators. Little shrinkage also always reduces the MSE of individual predictions for all three RR estimators; however, only the naive estimator that shrinks toward 1/2 retains this property for any generalized MSE (GMSE). In contrast, for the two RR estimators that shrink toward the common mean probability, there is always a GMSE for which even a minute amount of shrinkage increases the error. These theoretical results are illustrated on a numerical example. The estimators are also applied to a real data set, and practical implications of our results are discussed.     

What entrepreneurs discover when creating opportunities? Insights from Skype and YouTube ventures

Although the scholarly conversation about how entrepreneurial opportunities emerge has suggested that entrepreneurs both discover and create opportunity components, specific knowledge about what components are discovered is lacking. In this research, we use an exploratory case study to investigate the opportunity creation process. We found that entrepreneurs discover several opportunity-related components based on the prior experience and knowledge of other entrepreneurs. Drawing on the evidence from these exploratory cases, we identify three important types of components that entrepreneurs creatively recombine within an emerging opportunity: technology stack, business model, and product and service design architecture. These findings have important implications for our understanding of entrepreneurial bricolage and entrepreneurial recycling, and their connection to the process of opportunity creation.     

Institutional environment for entrepreneurship in rapidly emerging major economies: the case of Brazil,China, India,and Korea

The country institutional profile (CIP) construct has become the most widely used conceptualization of institutional environment for entrepreneurship. This construct is frequently employed to study institutional forces influencing entrepreneurial activity at the national level. However, relatively little is known about the cross-national equivalence of the construct. Moreover, the institutional environment for entrepreneurship in emerging economies remains largely under-explored. To address these issues, in the current study, we used the most frequently utilized CIP scale to collect data from 809 young adults in four rapidly emerging countries: Brazil, China, India, and South Korea. We examined the invariance of the CIP construct and unraveled differences in perceived institutional profiles among these rapidly emerging economies. Results support the CIP construct as largely invariant in the four REME countries and revealed important differences in specific aspects of institutional environments in these countries. Implications for future research and practice are discussed.     

The Influences of Economic and Technology Policy on the Dynamics of New Firm Formation

This study attempts to reveal how macroeconomic and technology policies that encompass the opportunity and individual drivers of entrepreneurship explain the dynamics of new firm formation in a country. To do so we rely on the Schumpeterian, industrial organization, and labor economics traditions of entrepreneurship, and performed an exploratory test with longitudinal U.S. data from 1968 to 1993. The results of this study suggest that R&D investments, patents, economic concentration, pro-competition policy, and labor mobility are important areas in which government policy can influence the intensity of new firm formation.     

The innovation and economic consequences of knowledge spillovers: fit between exploration and exploitation capabilities,knowledge attributes,and transfer mechanisms

The purpose of this study is to investigate the moderating roles of the attributes and transfer mechanisms of knowledge in the relationship between organisational capabilities and innovation and economic performance. Regression analysis on a sample of 120 Taiwanese firms was used to test our model. The findings suggest that the organisational capabilities of exploration and exploitation are positively related to innovation and economic performance. The effect of exploration on performance is positively moderated by tacit knowledge and adaptation knowledge transfer mechanisms. In contrast, exploitation is a stronger predictor of performance when organisations acquire well-defined knowledge and use replication knowledge transfer mechanisms.     

When should entrepreneurs expedite or delay opportunity exploitation?

We theorize on the performance implications of the timing at which entrepreneurs stop exploring their business opportunities and start exploiting them. Using an optimal-stopping approach, we characterize the time when exploitation should begin based primarily on when an entrepreneur's ignorance has been sufficiently reduced through knowledge accumulation. This “ignorance threshold” captures a tradeoff between the time needed to increase legitimacy and the necessity to act now to minimize competition. Changes in legitimacy and competition are based on how entrepreneurs manage their knowledge (tacit versus explicit) under differing degrees of novelty for the business opportunity. These changes, in turn, impact the performance and timing of opportunity exploitation.
