Immigration and economic welfare: resource and environmental aspects

"The relation between immigration and the economic welfare of residents is analyzed for resource-rich economies (such as Australia) both under competitive conditions and when various distortions are present. Immigration provides efficiency gains for residents under distortion-free competition for standard 'gains from trade' reasons. Such reasons, however, tend to be ignored by immigration and 'optimal population' theorists who raise the issue of restricting immigration without explicitly referring to the distortions. In situations where distortions and externalities are present, we argue that it is generally preferable to devise policies which specifically target the distortions than to restrict immigration."     

Measuring the productive efficiency of a group of firms

While the conventional Farrell-Färe approach to efficiency measurement can identify the most inefficient firms, it fails to consider the efficiency of a group of firms thoroughly. This paper introduces efficiency measures that can be used to find the efficiency of a group of firms and pinpoint whether the group inefficiency is due to inefficiency inside or outside individual firms. Furthermore, a new way of finding the revenue maximum shadow price vector is introduced to compute the allocative efficiency of individual firms when price data are not available.     

Does geographic dispersion affect firm valuation?

We find that the geographic dispersion of a corporation affects its firm valuation. Firms with subsidiaries located in different regions of the United States experience a valuation discount of 6.2% after controlling for the impact of both global and industrial diversifications. The valuation discount increases as firms expand their operations to different regions nationwide. Results show that firms with more anti-takeover provisions are more likely to be geographically diverse, and that these firms experience greater value discounts compared with their counterparts with fewer such provisions. Our overall evidence suggests that the geographic location of corporate activities is an essential component of corporate policies and has important market valuation implications.     

Quarterly beta forecasting: An evaluation

Ever since the inception of betas as a measure of systematic risk, the forecast error in relation to this parameter has been a major concern to both academics and practitioners in finance. In order to reduce forecast error, this paper compares a series of competing models to forecast beta. Realized measures of asset return covariance and variance are computed and applied to forecast beta, following the advances in methodology of Andersen, Bollerslev, Diebold and Wu [Andersen, T. G., Bollerslev, T., Diebold, F. X., & Wu, J. (2005). A framework for exploring the macroeconomic determinants of systematic risk. American Economic Review, 95, 398–404; and Andersen, T. G., Bollerslev, T., Diebold, F. X., & Wu, J. (2006). Realized beta: Persistence and Predictability. In T. Fomby & D. Terrell (Eds.), Advances in Econometrics, vol 20B: Econometric Analysis of Economic and Financial Times Series., JAI Press, 1–40.]. This approach is compared with the constant beta model (the industry standard) and a variant, the random walk model. It is shown that an autoregressive model with two lags produces the lowest or close to the lowest error for quarterly stock beta forecasts. In general, the AR(2) model has a mean absolute forecast error half that of the constant beta model. This reduction in forecast error is a dramatic improvement over the benchmark constant model.     

A method for generating uniformly scattered points on the <Emphasis Type="Italic">L</Emphasis><Subscript><Emphasis Type="Italic">p</Emphasis></Subscript>-norm unit sphere and its applications

Tashiro (Ann Inst Stat Math 29:295–300, 1977) studied methods for generating unform points on the surface of the regular unit sphere. The L _p -norm unit sphere is a generalization of the regular unit sphere. In this paper we propose a method associated with an algorithm for generating uniformly scattered points on the L _p -norm unit sphere and discuss its applications in statistical simulation, representative points of a wide class of multivariate probability distributions and optimization problems. Some examples are illustrated for these applications.

Why Does the US Face Greater Disadvantages in the Trade War with China?

The rhetoric used by President Trump regarding the trade war against China is rife with misinterpretation. The actual American trade deficit with China is much lower if evaluated in the correct terms of value‐added. The deficit is mainly a result of insufficient domestic US savings. In addition, as the US dollar is an international currency which is being increasingly held as a result of increases in world population, income, prices and transaction intensity, Americans can benefit from having trade deficits of hundreds of billions of US dollars each year. My analysis, as well as a model of the Bank of England, reveals that the trade war is not only mutually harmful but also actually hurts America more than China. The Thucydides Trap is likely avoidable in the current nuclear era of assured mutual destruction and because China, facing many structural impediments, is still far behind America in technology and military power.     

The spatial characteristics of inland transport hubs: evidences from Southern India

This paper investigates the spatial characteristics of inland transport hubs with evidence from the users’ choice of dry ports in cargo exportation in Southern India. The findings indicate that the current solution, where shippers often choose dry ports located closest to their production base, is not the optimal solution in terms of the minimisation of transport cost, mainly due to government policies and dry port’s inability in providing value-added services to shippers. This study provides important insight on the major attributes in explaining the spatial characteristics of inland transport hubs, especially in developing countries.     

China's post-economic reform growth: The role of FDI and productivity progress

China has become the top FDI destination among all developing countries and remained host to the world's largest share of foreign direct investment receipts since its accession to the WTO in 2001. Given the impressive growth performance and FDI influx into China, the two globalized delta economies (GDEs), Pearl River Delta (PRD) and Yangtze River Delta (YRD), have continued to out-perform all other regions in China in terms of FDI absorption and growth. The role that inward FDI plays in the process of regional development and the exact channels through which economic growth would be affected are investigated by panel data estimations of the GDEs at the city level since China's economic opening and reform. This research shows consistent results with some recent findings in other developing countries in that FDI exerted spillover effects and affected productivity (TFP) growth of the recipients. While TFP was found to be increasing overtime in the GDEs cities and facilitated economic growth in both PRD/YRD regions, major technology- and knowledge-related factors including R&D and human capital other than FDI also played critical roles in TFP enhancement and regional growth. The endogeneity of TFP and the simultaneous relations of FDI in affecting TFP and output growth are also addressed in this regard.
