Entrepreneurship and Growth: Evidence from China

This paper examines the impact of entrepreneurship on economic growth by using a panel data set of 29 provinces in China over 20 years. Two indicators of entrepreneurship are defined and introduced into the traditional growth regression framework that is estimated using the system generalized method of moments. We also use the ratio of staff and workers of state-owned enterprises and per capita sown land area as the instrumental variables to identify the causal effect of entrepreneurship on economic growth. Our results suggest that entrepreneurship has a significant positive effect on economic growth and this finding is robust even after we control for other demographic and institutional variables. Our study provides some evidence that may be used as a basis for evaluating the effect of China’s policy on private business which has been increasingly relaxed since the late 1970s.

Access to Banking Services and Money Transfers by Mexican Immigrants

Increased access to the U.S. financial system through banks’ recognition of the ‘matrícula consular’ identification card may encourage Mexican immigrants to save and transfer more money home. Using data from the Mexican Migration Project, we examine whether immigrants with bank accounts in the U.S. between 1970 and 2002 sent more funds to Mexico than their unbanked counterparts. While having a U.S. bank account does not raise monthly remittances by Mexican immigrants, it boosts the amount brought back home by more than $6000 per trip. These findings suggest that increased usage of banks by immigrants may enhance future flows of funds to Mexico.

Noise vs. News In Equity Returns

What role does noise play in equity markets? Answering this question usually leads immediately to specifying a model of fundamentals and hence the pervasive joint hypothesis quagmire. We avoid this dilemma by measuring noise volatility directly by focusing on the behavior of country closed-end funds (CCEF’s) during foreign (i.e., non-U.S.) holidays – for example, the last days of Ramadan in Islamic countries. These holiday periods are times when the flow of fundamental information relevant to foreign equity markets is substantially reduced and hence trading of CCEF’s in U.S. markets can be responding only weakly, if at all, to fundamental information. We find that, controlling for the effects of industry and global shocks and of the overall U.S. market, there remains a substantial amount of noise in the equity returns of U.S. CCEF’s. In the absence of noise, the noise ratio statistic would be near zero. However, our results indicate statistically significant departures from zero, with values averaged over all U.S. CCEF’s ranging from 76-84%xx depending on assumptions about the leakage of information during holiday periods and kurtosis. Noise is negatively related to institutional ownership of U.S. CCEF's and is much less important for U.K. CCEF's. The lower levels of noise for matched U.K. and U.S. CCEF’s provide some initial evidence that the U.K. securities transaction tax is effective in reducing stock market noise.

Export-Oriented FDI, the Euro, and EU Enlargement

Since 1999, the UK’s share of FDI heading into Europe has declined dramatically, while the Euro-Zone’s share has increased. I argue that the timing of this divergence is not coincidental. The formation of the Euro-Zone has eliminated nominal exchange rate volatility between member-states, increasing export market access intra-union. For source countries outside of Europe, Euro-Zone countries have become more attractive destinations for export-oriented FDI, as operations within the union are insulated from currency fluctuations. As exchange rate volatility between a non-Euro country and local export markets increases, or as the market size of the euro-zone increases, more and more investment will be diverted towards Euro-Zone countries. This theory is tested in two stages using detailed data on the operations of foreign affiliates of US multinationals across seventeen European countries from 1983 – 2004. A host country’s export market access is first estimated with an augmented gravity model. This export series is then included in a dynamic panel with US to host market exchange rate volatility and a range of FDI determinants to explain inflows of FDI from the US to European countries. Potential endogeneity issues are addressed using the Arellano and Bond (1991) GMM procedure. The ability to export from a particular host country has a positive and significant effect on inflows of FDI. Additionally, unobserved features of Euro-Zone membership (beyond the elimination of currency risk) have a positive effect on inflows. A counterfactual experiment sheds light on how much FDI the UK “lost” by not adopting the euro in 1999. Re-estimating the trade and FDI relations under the assumption that the UK had adopted the euro, I estimate that the UK has lost approximately $33 billion (2% of GDP) worth of FDI from the US. Similarly, the flight of FDI to the new EU accession countries has been slowed by these countries staying out of the Euro-Zone.

The Effects of State Policy Design Features on Take Up and Crowd Out Rates for the State Children’s Health Insurance Program

We evaluate the effects of state policy design features on SCHIP take up rates and on the degree to which SCHIP benefits crowd out private benefits. The results indicate that overall program take up rates range from 10.1 to 10.5 percent. However, there is considerable heterogeneity across states, suggesting a potential role of inter-state variation in policy design. We find that several design mechanisms have significant and substantial positive effects on take up. For example, eliminating asset tests, offering continuous coverage, simplifying the application and renewal processes, and extending benefits to parents all have sizable and positive effects on take-up rates. Mandatory waiting periods, on the other hand, consistently reduce take-up rates. In all, inter-state differences in outreach and anti-crowd out efforts explain roughly one quarter of the cross-state variation in take-up rates. Concerning the crowding out of private health insurance benefits, we find that between one quarter and one third of the increase in public health insurance coverage for SCHIP eligible children is offset by a decline in private health coverage. We find little evidence that the policy-induced variation in take-up is associated with a significant degree of crowd-out, and no evidence that the negative effect on private coverage caused by state policy choices is any greater than the overall crowding out effect. This suggests that states are not augmenting take-up rates by enrolling children that are relatively more likely to have private health insurance benefits.State Children’s Health Insurance Program (SCHIP), Crowd Out, Take Up

POVERTY AND THE MANAGEMENT OF NATURAL RESOURCES:A MODEL OF SHIFTING CULTIVATION

It is frequently asserted in the environment/development literature that severe poverty causes the neglect of worthwhile investments, resulting in deforestation and other resource degradation. While microeconomic theory does suggest a relationship between poverty and the evaluation of investments, the environmental impact is not so simple. This paper develops a dynamic theory of “shifting cultivation,” with special attention to an environmental impact variable: the length of time a given field is cultivated before a shift to the next. The model indicates that poverty reduction will lead in some ways to accelerated extraction of a natural resource, but also to a longer extraction period. The results therefore provide support for claims of an indirect environmental benefit from the primary goal of alleviating rural poverty. The impact of discount rates, prices, and other parameters are also explored.

Attracting and Retaining Teachers in High-Need Schools: Do Financial Incentives Make Financial Sense?

This study synthesizes what we know and do not know about policies to attract and retain teachers in high-need schools and assesses the relative cost-effectiveness of two types of policies. Research consistently shows that teacher quality is likely to be lower in schools with higher proportions of students from disadvantaged backgrounds. This pattern is likely a result of several factors but the most well-documented is teachers’ mobility choices within and across districts. Although there are numerous programs across the country intended to attract and retain highly-skilled teachers in high-need schools, there is very little assessment of their effectiveness. Given the lack of evidence on specific interventions, I use the results from existing studies of teacher mobility and attrition to compare the effect of salary incentives and induction or mentoring programs. Although financial incentives are arguably the most straightforward policies for states and districts to adopt, high-need schools may be better served if policymakers and researchers devoted more attention to more cost-effective alternatives.
