LM Tests for Functional Form and Spatial Correlation

This paper derives Lagrangian Multiplier tests to jointly test for functional form and spatial error correlation. In particular, this paper tests for linear and loglinear models with no spatial error dependence against a more general Box-Cox model with spatial error correlation. Conditional LM tests and modified Rao-Score tests that guard against local misspecification are also derived. These tests are easy to implement and are illustrated using Anselin's (1988) crime data. The performance of these tests are also compared using Monte Carlo experiments.

Prediction in the Panel Data Model with Spatial Correlation: The Case of Liquor

This paper considers the problem of prediction in a panel data regression model with spatial autocorrelation in the context of a simple demand equation for liquor. This is based on a panel of 43 states over the period 1965-1994. The spatial autocorrelation due to neighboring states and the individual heterogeneity across states is taken explicitly into account. We compare the performance of several predictors of the states demand for liquor for one year and five years ahead. The estimators whose predictions are compared include OLS, fixed effects ignoring spatial correlation, fixed effects with spatial correlation, random effects GLS estimator ignoring spatial correlation and random effects estimator accounting for the spatial correlation. Based on RMSE forecast performance, estimators that take into account spatial correlation and heterogeneity across the states perform the best for one year ahead forecasts. However, for two to five years ahead forecasts, estimators that take into account the heterogeneity across the states yield the best forecasts

Productivity effects of public capital maintenance: Evidence from U.S. states

This article assesses the productivity effects of infrastructure operation and maintenance (O&M) spending by state and local governments in the 48 contiguous U.S. states over the period 1978-2000. We explicitly account for transboundary spillovers of capital and O&M spending and follow a semiparametric methodology that allows us to estimate state-specific output elasticities. We find strong evidence that in all 48 states the cross-state spillover effects of O&M outlays on productivity exceed their within-state impacts and are substantially higher than the spillover effects of capital expenditure.

Institutional change and corporate governance diversity in China’s SOEs

This study investigates the impact of different types of state ownership on corporate governance, with particular reference to state-owned enterprises in China. Our finding confirms that Chinese institutional reforms have produced diversified state ownership regimes. We find that different types of government ownership exert different influences on board independence, ownership structure, and executive shareholding. We contribute to corporate governance research by challenging conventional definition of state ownership and propose that corporate governance studies should incorporate changing institutional environments in emerging economies.

Cointegration of Matched Home Purchases and Rental Price Indexes –Evidence from Singapore

This paper exploits the homogeneity feature of the Singapore private residential condominium market and constructs matched home purchase price and rental price series using the repeated sales method. These matched series allow us to conduct time series analysis to examine the long-term present value relationship in the housing market. Three key findings are obtained. First, we fail to establish a cointegrating relationship between the home purchase price and rental price based on nationally estimated indexes. Second, area-specific indexes demonstrate strong cross-correlations, invalidating the use of first generation panel unit root tests that ignore these cross-correlations. Third, Pesaran’s CIPS test indicates that the unit root hypothesis is rejected for the first difference of both indexes. We also do not reject the hypothesis that area-specific home purchases and rental price indexes are cointegrated with a cointegrating vector (1,-1)

Economic growth and inequality : the role of fiscal policies

This paper analyses the impact of different instruments of fiscal policy on economic growth as well as on income inequality, using an unbalanced panel of 43 upper-middle and high income countries for the period 1972-2006. We consider and estimate two individual equations explaining growth and inequality in order to assess the incidence of different fiscal policies. Firstly, our approach considers imposing orthogonal assumptions between growth and inequality in both equations, and secondly, it allows growth to be included in the inequality equation, and inequality to be included in the growth equation. The empirical results suggest that an increase in the size of government measured through current expenditures and direct taxes diminishes economic growth while reducing inequality, being public investment the only fiscal policy that may break this trade-off between efficiency and equity, since increases in this item reduces inequality without harming output. Therefore, the results reflect that the trade-off between efficiency and equity that governments often confront when designing their fiscal policies may be avoided

Democracy, Financial Openness, and Global Carbon Dioxide Emissions: Heterogeneity Across Existing Emission Levels

The determinants of CO2 emissions have attracted many researchers over the past few decades. Most of studies, however, ignore the possibility that effect of independent variables on CO2 emissions could vary throughout the CO2 emission distribution. We address this issue by applying quantile regression methods. We examine whether greater democracy and more financial openness consistently reduce emissions among the most and least emission nations. Our results show that the effect of democracy on CO2 emissions is heterogeneous across quantiles. Among the most emissions nations, greater democracy appears to reduce emissions, but more financial openness does not appear to reduce it

Can Perceived Support for Entrepreneurship Keep Great Faculty in the Face of Spinouts?

Despite the recent increase in academic entrepreneurship research, we still know relatively little about the degree of involvement of academic inventors in university spinouts. In this study, we distinguish between academic inventors who leave the university after the creation of a spinout (academic exodus) and those who maintain their university affiliation (academic stasis). Drawing from the literature on innovation-supportive climates and from organizational support theory, we argue that perceptions of institutional support and departmental norms regarding entrepreneurship are associated with the exodus versus stasis decision. We find that inventors who have higher perceptions of institutional support for entrepreneurship are less likely to leave. This relationship is enhanced by perceptions of favorable departmental norms toward entrepreneurship. We discuss the implications of our work for the literature on academic entrepreneurship, innovation-supportive climates, and perceived organizational support. Our study has clear policy implications for universities, policymakers, and funders who aim to stimulate academic entrepreneurship, but are concerned about losing entrepreneurial faculty. Specifically, we advise universities and policymakers to actively support academic inventors wishing to spin out and to monitor this support in a customer-friendly manner, in order to ensure that the inventors' perceptions of support are favorable. It is also important for universities to look out for inconsistencies between a supportive environment for entrepreneurship at the institutional level and unfavorable norms toward entrepreneurship at the departmental level; such inconsistencies can lead good faculty members out of academia. More broadly, universities can pursue an aggregation strategy that aims to retain both a research and commercialization identity while building strong links between them

Informed trading by foreign institutional investors as a constraint on tunneling: evidence from China

Research Question/Issue: This paper investigates how the trading activities of foreign institutional investors (FIIs) affect the tunneling activities of controlling shareholders in an emerging economy (China). Research Findings/Insights: We use an unbalanced panel dataset of 167 FIIs with investments in Chinese real estate firms during the period 2003 to 2011, which gives us 1006 firm-year observations in total. We find strong support for our hypothesis of an inverted U shaped relationship between FII trading turnover and the extent of tunneling by controlling shareholders. Theoretical/Academic Implications: In many emerging economies, the institutional environments for investor protection are weak. Powerful controlling shareholders may take the opportunity to extract private benefits via tunneling activities to the detriment of minority shareholders, and informed minority investors may also take advantage of less well-informed investors. There are thus multiple principal-principal agency conflicts. FIIs are a particularly important group of informed investors. On the one hand, large-scale aggressive trading by FIIs should drive stock prices to fundamentals, provide market discipline to management, and thus limit tunneling. On the other hand, FIIs may opt to exploit their private knowledge to gain trading profits at the expense of uninformed investors, and implicitly support tunneling. We highlight these potential effects, and demonstrate empirically an inverted U-shaped relationship between FII trading turnover and the extent of tunneling. Practitioner/Policy Implications: Tunneling is a serious issue, particularly in emerging economies where the institutional arrangements for minority investor protection are often weak. FII involvement may enhance market discipline, but may also exacerbate the problem so policy-makers need to guard against potential adverse effects. An ownership cap on FII shareholdings is unlikely to be effective, but policy-makers might strengthen QFII license revocation policies and issue more licenses to promote competition among FII
