The location determinants of FDI in the GCC countries

This paper studies the location determinants of FDI flows to the GCC countries, along Dunning's [Dunning, J., 1981. International Production and the Multinational Enterprise. Allen & Unwin, London] OLI paradigm. The paper uses panel data for the period 1980–2002. Panel data model estimates show that oil potential, measured by oil reserves, and oil utilization, measured by oil production, have a surprisingly negative influence on FDI flows, contrary to expectations about positive association between GCC oil resources and FDI flows. However, the relative degree of oil utilization, measured by oil production relative to oil reserves, has a positive influence on inflows. Similar to oil potential and oil utilization, oil price has a negative influence. Estimates also show that while institutional quality, trade openness and infrastructure development encourage FDI flows, human capital significantly discourages them.     

Trade wedges,inventories, and international business cycles

The large, persistent fluctuations in international trade that cannot be explained in standard models by changes in expenditures and relative prices are often attributed to trade wedges. We show that these trade wedges can reflect the decisions of importers to change their inventory holdings. We find that a two-country model of international business cycles with an inventory management decision can generate trade flows and wedges consistent with the data. Moreover, matching trade flows alters the international transmission of business cycles. Specifically, real net exports become countercyclical and consumption is less correlated across countries than in standard models. We also show that ignoring inventories as a source of trade wedges substantially overstates the role of trade wedges in business cycle fluctuations.     

Aid for trade, infrastructure, and growth

Aid for trade is a new foreign aid initiative to assist recipient countries to build trade-related infrastructure. We formulate a small-country, two-good (i.e., investment and consumption goods), two-factor (i.e., capital and labor) endogenous growth model with learning by doing and intersectoral knowledge spillovers, where the import transport cost depends inversely on public infrastructure. Focusing on the case where the country is incompletely specialized and imports the investment good, we show that a permanent increase in the recipient’s aid/GDP ratio raises the steady-state growth rate if and only if the investment good is more labor-intensive.     

中国与"一带一路"沿线国家出口贸易研究——基于汇率变动、外贸依存度的视角

引入汇率变动引力模型,采用“一带一路”沿线64个国家2002-2015年面板数据,研究汇率变动和外贸依存度对出口贸易的影响,结果显示：汇率变动不是影响中国对“一带一路”沿线国家出口贸易的最重要因素,人民币升值促进了出口贸易,原因在于中国“一带一路”沿线国家的汇率变动不是很大;外贸依存度对出口贸易影响显著且存在双重门槛效应,外贸依存度越小,出口潜力越大;两国之间距离对出口贸易有显著负向影响;缔结自由贸易协定对出口贸易的影响尚未显现。因此,我国应保持人民币汇率基本稳定,以外贸依存度大小分类实施不同贸易政策,继续推进“一带一路”国家基础设施建设,并细化自由贸易协定。     

Gas transportation, geopolitics and future market structure

Recent studies have shown the important role of geography, politics and technology for the evolution of markets for natural gas. Gas market differs from other markets due to high share of transport and infrastructure costs. Since investment is location specific, it involves also geopolitical aspects as a consequence. Future market structure becomes path dependent on the investment decisions, particularly in gas infrastructure (pipelines and LNG). Another important aspect that shapes future gas market is heterogeneity in reserve-production ratios across gas producing countries that will eventually lead to the emergence of narrow oligopoly formed by countries with the largest reserves: Russia, Iran and Qatar. The goal of this paper is to analyse a long run gas game. There exist several time scales, and by backward induction we arrive at the conclusion that some time during the 21st century (we name it long run) there will be an oligopoly consisting of only three major gas reserve holders: Russia (26%), Iran (15%) and Qatar (14%). They will face the demand from three major gas importers: EU, USA and Core Asia. While the development paths and market structures are highly uncertain in the middle run (when temporal competition with rivals having 3% or less of gas reserves is feasible), the cloud of uncertainty shrinks in the long run. But investment strategies of major players in the middle run will determine the topology of gas infrastructure in the long run. All the players have a vector of strategic choices where geography, politics and technology set their limitations. Putting it in a simple formal framework, we can say that players choose: intensity of exploitation and shares of investment in transport infrastructure (LNG and location-specific pipelines). Geographical analysis of gas fields of Russia shows that it has moderate flexibility, but still can control the future share of LNG and pipeline flows to Europe and Asia. Pipelines to EU are slightly preferred to pipelines to Asia but political aspects may play crucial role. Qatar is likely to invest only in LNG, but has the flexibility in the speed of its field exploitation (it may be lower that for Russia). Iran has the highest technological and geographical freedom in choices. Future market structures for gas can vary from oligopolistic to monopolistic–monopsonistic relationship, with possibly different prices.     

PORTFOLIO CHOICES,CONSUMPTION, AND PRICES IN A MARKET WITH DURABLE ASSETS

Recent research in investments has focused almost exclusively on financial assets such as corporate stocks. Although durable assets constitute an important part of investors' holdings, little effort has been made to explore their role in individuals' investments decisions and on assets pricing. This paper establishes results concerning the role of durable assets in the determination of optimum portfolio choices. The paper explores the effect of consumption considerations related to the service flows generated by durable assets on optimum portfolio considerations and asset prices. The main result is tied to the existence, or lack thereof, of efficient rental markets. In the absence of rental markets (or with restrictions on renting), investors' portfolio choices are not independent of consumption considerations as they are assumed to be in the standard CAPM. Individuals may thus hold different portfolios, and prices reflect the owner's inability to trade consumption flows. Under perfect market assumptions with unrestricted rental markets, optimum portfolio choices are undistinguishable from those implied by the standard CAPM in the sense that they are mean-variance efficient and identical for all individuals. Consumption is adjusted by trading service flows in the rental market. Prices, and the price of risk, however, reflect the existence of durable assets service flows as well as the risks involved in trading these flows in the rental market. In the model, risky rental income is introduced by uncertain rental costs. Equilibrium rental rates, an important part of the return expected from holding durable assets, are determined in the context of the mean-variance framework as a function of return and undiversifiable risk.     

Trade costs and multimarket collusion

Contrary to conventional wisdom, this article argues that trade liberalization may facilitate collusion and reduce welfare. With the help of a duopoly model in which firms interact repeatedly in multiple markets, we first show that, if trade costs (i.e., tariffs/transport costs) and discount factors are not too high, efficient cartel agreements necessitate the cross‐hauling of goods, as that entails lower deviation incentives. In this setting, we then demonstrate that reciprocal trade liberalization always raises total output when trade costs are within a range whose lower bound exceeds a threshold level, but may reduce total output (and thus be pro‐collusive) when trade costs are below that threshold level.     

Trade costs, firms and productivity

This paper examines the response of U.S. manufacturing industries and plants to changes in trade costs using a unique new dataset on industry-level tariff and transportation rates. Our results lend support to recent heterogeneous-firm models of international trade that predict a reallocation of economic activity towards high-productivity firms as trade costs fall. We find that industries experiencing relatively large declines in trade costs exhibit relatively strong productivity growth. We also find that low-productivity plants in industries with falling trade costs are more likely to die; that relatively high-productivity non-exporters are more likely to start exporting in response to falling trade costs; and that existing exporters increase their shipments abroad as trade costs fall. Finally, we provide evidence of productivity growth within firms in response to decreases in industry-level trade costs.     

Evaluation of the biases in execution cost estimation using trade and quote data

We use order data to assess the accuracy of execution cost estimation with trade and quote data. For our sample, estimates of the effective spread overstate actual execution costs by up to 17%. The biases result from errors in the inference of the trade direction and errors in the assignment of the benchmark quote. We find the accuracy of two popular trade direction algorithms improve marginally when trades are not lagged 5 seconds. Evaluation of the biases in execution cost measurement reveal the Ellis et al. (Journal of Financial and Quantitative Analysis (2000) 529) trade direction algorithm, combined with assigning benchmark quotes contemporaneous with trades, provides the least amount of bias. In general, biases are lower for relative effective spread estimates than effective spread estimates.     

On the sensitivity of the volume and volatility of bilateral trade flows to exchange rate uncertainty

We present an empirical investigation of the hypotheses that exchange rate uncertainty may have an impact on both the volume and variability of trade flows by considering a broad set of industrial countries' bilateral real trade flows over the period 1980–1998. Similar to the findings of earlier theoretical and empirical research, our first set of results shows that the impact of exchange rate uncertainty on trade flows is indeterminate. Our second set of results provides new and novel findings that exchange rate uncertainty has a consistent positive and significant effect on the volatility of bilateral trade flows, helping us better understand macroeconomic volatility.     

中国城际高铁与商业信用供给——基于准自然实验的研究

本文利用中国城际高铁开通对公司产品质量保证动机产生的外生变化来考察其如何影响公司的商业信用供给决策。高铁开通通过降低运输成本,提高了公司与客户之间的交易量,不仅可以降低公司与客户之间的信息不对称,还可以促使公司提高产品质量,削弱了公司为了保证产品质量而提供商业信用的动机。借助高铁开通在时间和空间上错列发生的特征,构建准自然实验情境,本文使用双重差分方法的检验,结果表明高铁开通使公司商业信用供给减少约3.51%。研究发现,交易量提高是高铁开通减少公司商业信用供给的重要渠道。进一步分析发现,对于事前信息不对称程度较大、关系专用性投资水平较高和产品质量保证需求较低的公司,高铁开通导致公司商业信用供给减少更多。本文研究为商业信用供给的产品质量保证理论提供了进一步的补充和发展,研究结论对于理解交通基础设施的经济效应以及公司商业信用供给决策的影响因素具有一定的启示意义。     

The Role of Infrastructure in Mexican Economic Reform

This article estimates the relationship between the provisionof public infrastructure and private output in sixteen sectorsin Mexico. The sector-specific cost functions depend on wages,the cost of capital, and the nominal values of the stocks ofthree types of infrastructure: electricity, transport, and communications.The article concludes that infrastructure in electricity andcommunications generally reduces the cost of sectoral production,but transportation infrastructure tends to increase costs ofsectoral production. It appears that Mexican public expenditureon electricity and communications has enhanced the productivityof private production, but expenditure on transport may actuallyhave had a detrimental effect on private output. In addition,although in general labor and infrastructure are substitutes,in the case of electricity and communications infrastructure,capital and infrastructure are complements. In the case of transportinfrastructure these conclusions are reversed.     

Exchange-rate volatility and industry trade between the U.S. and Malaysia

Previous research that investigated the impact of exchange rate volatility on the trade flows of Malaysia concentrated only on the aggregate exports of Malaysia to the rest of the world. In this paper we first concentrate on the trade flows between Malaysia and the U.S. After showing that exchange rate volatility has neither short-run nor long-run effect on the trade flows between the two countries, we disaggregate the trade data by industry and consider the experience of 101 U.S. exporting industries to Malaysia and 17 U.S. importing industries from Malaysia. While exchange rate volatility seems to have significant short-run effects on the trade flows of most industries, short-run effects translate into the long run only in a limited number of small industries.     

Adverse selection costs for NASDAQ and NYSE after decimalization

NYSE and NASDAQ completed their decimalization on January 29, 2001 and on April 9, 2001 respectively. In this paper, we compare adverse selection component of the bid–ask spread for NASDAQ and NYSE stocks after decimalization using the data from May 2001 and July 2001. We find that the adverse selection component of the bid–ask spread is significantly lower on NASDAQ than on NYSE, and these differences cannot be attributed to the differences in the characteristics of the stocks traded in the two markets. In addition, we find that the adverse selection costs increase with trade size on NYSE, however there is no monotonic pattern observed for NASDAQ stocks. Lastly, we report that although the order flows arrived in the two markets are significantly different, they can at best explain a small portion of the observed differences in adverse selection costs.     

Trade, production sharing, and the international transmission of business cycles

Countries that are more engaged in production sharing exhibit higher bilateral manufacturing output correlations. We use data on trade flows between US multinationals and their affiliates as well as trade between the United States and Mexican maquiladoras to measure production-sharing trade and its link with the business cycle. We then develop a quantitative model of international business cycles that generates a positive link between the extent of vertically integrated production-sharing trade and internationally synchronized business cycles. A key assumption in the model is a relatively low elasticity of substitution between home and foreign inputs in the production of the vertically integrated good.     

Financing constraints, cash-flow risk, and corporate investment

Using an analytically tractable two-period model of a financially constrained firm, we derive an investment threshold that is U-shaped in cash holdings. We show analytically the relevant trade-offs leading to the U-shape: the firm balances financing costs for present and future investment, respectively. Our main argument is that financing costs today are more important than the risk of future financing costs. The empirically testable implications are that low-cash firms facing financing costs today are more reluctant to invest if they have less cash, or if their future cash flows are more risky. On the other hand, cash-rich firms facing no financing costs today invest in less favorable projects (i.e., forgo their real option to wait) if they have less cash, or if their future cash flows are more risky. The magnitude of these effects is amplified by the degree of market frictions that the firms are facing.     

How do natural and man-made disasters affect international trade? A country-level and industry-level analysis

This study examines the influence of disasters on international trade with a gravity equation model. Four types of disasters will be introduced: natural disasters, technological disasters, political risks, and financial crises. Existing literature implies that any type of disasters can either positively or negatively associated with international trade. The effects of disasters are different across the socioeconomic status of trade pairs and across industries as well as across different types of disasters. Results from country-level and industry-level show that natural disasters reduce international trade flows by raising trading and security costs and hardening borders. In contrast to previous findings, these results show that terrorism activities and technological disasters increase the international trade particularly between developed countries. The econometric specification controls unobserved characteristics of trade pairs and endogeneity problems. Managerial implications and future research are discussed.     

Regional Effects of Exchange Rate Fluctuations

We exploit differences across U.S. states' exposure to trade to study the effects of changes in the exchange rate on economic activity. Across states, trade-weighted exchange rate depreciations are associated with increased state exports, reduced state unemployment, and higher state hours worked. The effects are particularly strong during periods of economic slack. A multiregion model with interstate trade and labor flows, calibrated to match state-level trade data and migration flows, replicates the empirical relationship between exchange rates and unemployment. The high degree of interstate trade plays an important role in transmitting shocks across states in the first year, whereas interstate migration shapes cross-sectional patterns in later years. We use the model to study the regional effects of tariffs in the United States. The model suggests that a 25% Chinese import tariff on U.S. goods would be felt throughout the United States, even in states with small direct linkages to China, raising unemployment rates by 0.2 to 0.7 percentage points in the short run.

透明度变化对股票市场投资者委托单提交行为和交易成本影响研究

基于2003年12月8日沪深交易所交易前市场透明度改革背景,本文利用一家营业部的投资者报价和交易数据,研究同一个机构投资者和散户投资者在透明度改革前后委托单提交激进程度的变化,以及这种变化对其完成交易的成本的影响。我们发现,透明度改革前后,机构投资者的委托单提交激进程度都显著大于散户投资者的委托单提交激进程度。透明度增加以后,机构投资者的委托单激进程度显著减少,而散户投资者的委托单提交激进程度增加。同时发现,透明度增加以后,机构投资者通过分拆委托单,增加交易次数,导致完成交易的时间增加,但价格影响力基本没有变化,散户投资者的成交时间和价格影响力有显著改善。
