Diagnostic Tests of Cross‐section Independence for Limited Dependent Variable Panel Data Models*

This article considers the problem of testing for cross‐section independence in limited dependent variable panel data models. It derives a Lagrangian multiplier (LM) test and shows that in terms of generalized residuals of Gourieroux et al. (1987) it reduces to the LM test of Breusch and Pagan (1980) . Because of the tendency of the LM test to over‐reject in panels with large N (cross‐section dimension), we also consider the application of the cross‐section dependence test (CD) proposed by Pesaran (2004) . In Monte Carlo experiments it emerges that for most combinations of N and T the CD test is correctly sized, whereas the validity of the LM test requires T (time series dimension) to be quite large relative to N. We illustrate the cross‐sectional independence tests with an application to a probit panel data model of roll‐call votes in the US Congress and find that the votes display a significant degree of cross‐section dependence.     

A target's perspective on the effects of ATPs in takeovers after recognizing its choice in the process

The use of antitakeover provisions (ATPs) in corporate charters/bylaws has evoked substantial debate over their costs and benefits. While there are many empirical studies of their effects in takeovers, these studies have ignored the self selection issues introduced by studying completed transactions, which reflect the target's choice. We examine data on a sample of U.S. corporations and show that accounting for self selection leads to a more nuanced understanding of how ATPs influence target shareholder wealth. We show that the effect of ATPs is more on the likelihood of receiving a bid rather than the success of a bid and that the success of a takeover is driven primarily by the characteristics of the offer and offer process rather than by the characteristics of the target and its ATPs. Further, we document that prior empirical studies that ignore these issues have mis-estimated the economic and statistical significance of various ATPs on target shareholder wealth.     

Strategic implications of the Soviet‐North Korean alliance

Abstract

Globalization is commonly defined as a strict economic path by most previous works, but it is really a fuzzy concept with unrestrained dimensions. While the ideological location of an incumbent political party is a powerful predictor of its policy position, the role of a political party in the globalization-growth nexus has never been fully empirically investigated. By applying Pedroni's panel cointegration technique instead of a time-series or traditional panel data approach, this paper aims to empirically re-examine the co-movement and the causal relationship among economic growth, the overall globalization index, and its three main dimensions—economic, social, as well as political integrations—by using panel data for 23 Organization for Economic Cooperation and Development (OECD) countries for 1970 to 2006. Certainly, the political party variable is taken into account as the advanced test is promoted, and we finally discover that all variables move together in the long run. Based on the results of the panel causality test, though the evidence of short-run causality is very weak, it does show long-run unidirectional causality running from the overall index of globalization, economic globalization, and social globalization to growth. Finally, the critical role of the political party is deeply discussed in relation with our results.     

Money supply,interest rate,liquidity and share prices: A test of their linkage

The money supply impacts on interest rate and liquidity were first proposed in 1961 by Friedman, the late Nobel laureate. The liquidity effect has yet received unanimous empirical support. Also, research interest on liquidity subsided in the 2000s. Using quarterly data over 1960–2011 and simultaneous solution to a system of equations, this paper reports positive liquidity effect from money supply. By extending the system of equations with a liquidity equation and after controlling the effect of earnings, evidence is found of a significant positive effect from liquidity on share prices. Money supply is found to be endogenous as in post Keynesian theory. These findings, obtained after solutions to several econometric deficiencies in prior studies, provide clear verification of the endogenous money supply theory, money effect on liquidity and on the extension of the model for a liquidity effect on asset prices.     

The Role of the Judiciary in the Public Decision‐Making Process

Empirical work on the relationship between political corruption and the design of public institutions suggests that the structure of judiciaries is an important determinant of corruption. This study develops a simple political economic model to investigate the role of judicial oversight in the policy‐making process for corruption deterrence, focusing on two dimensions of quality of the judiciary, namely efficiency and integrity. Our analysis explicitly accounts for the possibility that, while being independent of the political authority, the judiciary itself may be vulnerable to pressure from special interests. We study endogenous policy‐making under complete information and provide general conditions for the existence of deterrence (zero‐bribe) equilibria. In particular we show that preserving the independence of judiciaries in corrupt societies proves crucial to the existence of corruption‐deterrence effects.     

Forecasting development outcomes under alternative surplus labour assumptions

Economic forecasts are useful to policymakers both as aids to planning, and as baselines against which counterfactual scenarios can be compared. However, policy makers should be aware that assumptions relating to model structure can influence forecast results. We explore the sensitivity of forecasts to one aspect of model structure important in modelling developing economies: surplus agricultural labour. We outline a framework for modelling surplus agricultural labour that relies on average product remuneration. We embed this within a model of a developing economy (the Philippines) characterized by surplus agricultural labour. We compare the results of two forecasts that differ in their treatment of the agricultural labour market. In the first, the surplus labour theory is activated, establishing average product remuneration in agriculture. In the second, the surplus labour theory is not activated, creating a failure to recognize average product remuneration in agriculture. By comparing the two simulations, we show that failure to model the presence of average product remuneration, when it would be appropriate to do so, has an impact that would be material to economic planners, leading them to: under-estimate agricultural employment; over-estimate GDP growth; and, over-estimate important policy variables (like tax revenue) that are related to GDP growth.
