Financial integration and the wealth effect of exchange rate fluctuations

Recent years have witnessed a large increase in international financial integration in the form of largely offsetting cross-holdings across countries. We assess how such financial leverage affects the international transmission of monetary shocks, and find that it leads to sizable welfare differentials that far exceed the impact due to nominal rigidities. We document the relevance of the exact nature of holdings, with bond holdings associated with larger effects than equity holdings. The impact of financial leverage on welfare is also sensitive to the extent of exchange rate pass-through and the substitutability between goods produced in different countries.     

Export prices,selection into exporting and market size: Evidence from China and India

This paper empirically analyses the export pricing behaviour of Chinese and Indian exporters when there is selection into exporting. Previous exchange rate pass-through estimates that did not take selection into account could be biased if selection into exporting is correlated with pricing strategy. We use 6-digit product-level data across high- and low-income export destinations over the period 1994–2007 and assess a number of determinants of the degree of pass-through of exchange rates to export prices, such as the level of external demand, exporter’s wage cost, degree of competition in export markets, currency volatility and the direction of currency movements. We find systematic differences in the pricing strategies of Chinese and Indian exporters while uncovering a selection bias in exports to high-income markets, although the pricing of exports to low-income markets is independent of the decision to export. Export prices do not increase systematically with the destination market per capita income, and tend to be less sensitive in shipments to advanced nations. Export prices of India are sensitive to the volatility of the trade-weighted nominal effective exchange rate (NEER), indicating heterogeneity in prices to maintain competitiveness, but not in China as volatility is insignificant given a fixed currency system. It is also revealed that a country with a relatively flexible currency regime and arms-length trade such as India is more likely to exhibit incomplete pass-through, whereas a country with an inflexible currency system and involved in outward processing trade is more likely to have full pass-through as shown in the case of China.     

Patience, persistence, and welfare costs of incomplete markets in open economies

We investigate the welfare implications of alternative financial market structures in a two-country endowment economy model. We obtain an analytic expression for the expected lifetime utility of the representative household when sovereign bonds are the only internationally traded asset, and we compare this welfare level with that obtained under complete asset markets. The welfare cost of incomplete markets is negligible if agents are very patient and shocks are not very persistent, but this cost is dramatically larger if agents are relatively impatient and shocks are highly persistent. For realistic cases in which agents are very patient and shocks are highly persistent, the welfare cost of incomplete markets is highly sensitive to the specific values of these parameters.     

上游补贴利益传递：经济学分析与法律规制 ——基于价格弹性理论的视角

价格弹性理论的分析表明,政府旨在消除国内生产商劣势的补贴通常不发生利益传递,而政府超额补贴必然引发利益传递,并且利益传递程度与投入产品的需求价格弹性呈反比关系。鉴于正向追踪投入产品的需求价格弹性不具有可操作性,上游补贴利益传递程度的量化应逆向回溯投入产品的市场价格。而在此类价格不存在或不合理时,无需构建调整价格,因为外部基准是相对客观、中立的选择。此外,利益传递应仅向上游追溯一个环节,并以投入产品的补贴数量为上限。     

Incomplete pass-through and the welfare effects of exchange rate variability

This paper considers the implications of incomplete exchange rate pass-through for optimal monetary and exchange rate policy. A two-country model is presented, which allows an explicit derivation of welfare functions in terms of a weighted sum of the second moments of producer prices and the nominal exchange rate. From a single country perspective, the optimal exchange rate variance depends on the degree of pass-through, the size and openness of the economy, the elasticity of labour supply and the volatility of foreign producer prices. Welfare may be decreasing or increasing in the volatility of the exchange rate.     

Co-movement among oil,stock, bond,and housing markets: An analysis of U.S., Asian,and European economies

This study explores the co-movement among oil and the stock, bond, and housing markets of the U.S. and major developed countries across Europe and Asia. The results indicate that oil is long-run integrated with each asset class, and that the extent of convergence has increased after the onset of the 2007–2009 global financial crisis (GFC). Moreover, oil contributes most heavily toward the common trends, implying that oil is the “leader” sector that drives each asset class toward long-run equilibrium relationships. Short-run analyses indicate that oil shocks induce a negative response in stock and housing returns and a positive reaction in bond returns, showing a tendency to become more intense and persistent after the GFC. When oil shocks are disentangled, the results indicate that supply and demand have heterogeneous effects on the three global asset classes. Over the long-run, demand shocks make the most significant contribution to the common trends and “lead” the other asset classes, whereas supply shocks have either a negligible or a weaker impact. Over the short-run, demand shocks positively impact the stock and housing markets and negatively impact bonds, while supply shocks induce negative and weaker impacts on all three asset classes.     

Firm-level volatility and exports

This paper shows that the share of exports in the total sales of a firm has a positive and substantial impact on the volatility of its sales. Decomposing the volatility of sales of exporters between their domestic and export markets, I show using an identification strategy based on a firm-specific geographical instrument that firms with a larger export share have more volatile domestic sales and less volatile exports. These empirical patterns can be explained using a model in which firms face market-specific shocks and short-run convex costs of production. In such a framework, firms react to a shock in one market by adjusting their sales in the other market. I point to strong evidence that output variations on the domestic and export market are negatively correlated at the firm level. This result casts doubts on the standard hypothesis that firms face constant marginal costs and maximize profits on their different markets independently of each other. Furthermore, it points to the caveat that sales volatility on a particular market only gives limited information about the size of shocks on that market.     

Should the exchange rate be a shock absorber?

This paper examines the welfare case for the exchange rate as a “shock absorber”, cushioning an economy in face of shocks to world demand for its good. We provide an example in which, although the exchange rate acts perfectly as a shock absorber, stabilizing output around the natural rate, and eliminating the impact of nominal rigidities, it may in fact be better to prevent the exchange rate from adjusting at all. The explanation for this is that, with incomplete international financial markets, the natural rate is inefficient; it does not respond enough to demand shocks. While fixing the exchange rate increases the volatility of consumption, the pro-cyclical nature of monetary policy under a fixed exchange rate allows for a more efficient composition of consumption between home and foreign goods. Furthermore, for the shocks examined, a welfare maximizing monetary rule always dampens exchange rate volatility relative to that of a free float, and in some cases may imply a fixed exchange rate.     

Unionized labor markets and globalized capital markets

This paper studies the effects of international integration of capital markets in a world where countries differ in their labor market institutions: one country has a perfectly competitive labor market while the other is unionized. We show that workers should favor autarky in the unionized country, but oppose it in the non unionized country and vice versa for owners of capital. Aggregate gains from integration, however, are negative. We also show that, under capital mobility, an increase in relative bargaining power of unions does not always improve workers' welfare.     

When NGOs go global: Competition on international markets for development donations

Why are many large non-governmental organizations (NGOs) becoming multinational entities? What are the welfare implications of this integration of markets for development donations? To answer these questions, we build a simple two-country model with horizontally differentiated NGOs competing in fundraising. We find that NGOs become multinational if the economies of scale in fundraising are sufficiently large. In that case, national NGOs in the smaller country disappear, while some national NGOs remain in the larger country only if country sizes are sufficiently different. Social welfare is higher in the regime with multinationals than under autarky.

Who bears the cost of a change in the exchange rate? Pass-through accounting for the case of beer

Nominal exchange rates are remarkably volatile. They ordinarily appear disconnected from the fundamentals of the economies whose currencies they price. These facts make up a classic puzzle about the international economy. If prices do not respond fully to changes in the nominal exchange rate, who bears the cost of such large and unpredictable changes: foreign firms, domestic firms, or domestic consumers? This study presents a new analysis of the sources of incomplete pass-through and then uses this analysis to re-examine its implications for social welfare. I develop and estimate a structural model that analyzes the sources of local-currency price stability for a particular industry. The model enables counterfactual simulations that quantify the relative importance of firms' local-cost components and markup adjustments in the incomplete transmission of exchange-rate shocks to prices and the effect of the exchange-rate shock on domestic and foreign firms' profits and on consumer surplus. The model is applied to a panel dataset of one industry with retail and wholesale prices for UPC-level products. I find that markup adjustments by manufacturers and the retailer explain roughly half of the incomplete transmission and local-cost components account for the other half. Foreign manufacturers generally bear a greater cost (or reap a greater benefit) following an exchange-rate-induced marginal-cost shock than do domestic consumers, domestic manufacturers, or the domestic retailer.     

Financial integration,specialization, and systemic risk

This paper studies the implications of cross-border financial integration for financial stability when banks' loan portfolios adjust endogenously. Banks can be subject to sectoral and aggregate domestic shocks. After integration they can share these risks in a complete interbank market. When banks have a comparative advantage in providing credit to certain industries, financial integration may induce banks to specialize in lending. An enhanced concentration in lending does not necessarily increase risk, because a well-functioning interbank market allows to achieve the necessary diversification. This greater need for risk sharing, though, increases the risk of cross-border contagion and the likelihood of widespread banking crises. However, even though integration increases the risk of contagion it improves welfare if it permits banks to realize specialization benefits.     

Exchange Rate Effects on Domestic Prices in Bulgaria and Poland: Progress in Making Markets?

The economic liberalization which has occurred in Central and Eastern Europe (CEE) over the past 15 years generally has involved establishing domestic markets and privatizing state‐owned firms, both with the intention of integrating the CEE economies into the global economy and allowing the benefits of competition to be realized. We explore how well this has been accomplished in two countries, Poland and Bulgaria, and the domestic conditions that contribute to its accomplishment. The sensitivity of domestic markets to international shocks, as reflected in exchange rate effects on domestic prices, may be viewed as an indicator of how integrated a country’s markets are into the global economy, and a proxy for competition in those markets. In explaining variation in exchange‐rate pass‐through, we examine the impact of market structure, economic liberalization and infrastructure as factors contributing to the development of competitive markets. We find that although integration into global markets can significantly increase market competitiveness, domestic factors also play a significant role.     

Differential pricing, parallel trade, and the incentive to invest

I consider the case for imposing uniform pricing on a monopolist in a setting where markets can be segmented according to differences in marginal costs and/or consumer demand. I also analyze the ex ante impact on incentives to invest in R&D. I show how two opposite trade-offs arise. When differential pricing is demand-based, uniform pricing has good ex-post welfare properties but leads to lower investment ex ante. Conversely, when differential pricing is cost-based, uniform pricing has bad ex-post welfare properties but leads to higher investment ex ante.     

Labour Market Institutions and Household Consumption Insurance within OECD Countries

This paper tests empirically whether the effect of idiosyncratic income shocks on aggregate consumption depends on institutional features of national labour markets. The results show that, in a sample of 15 OECD countries, institutional heterogeneity is a significant determinant of the response of household consumption to country‐specific income shocks. This is consistent with the idea that institutionally provided social insurance may help increase income stability when people differ in their ability to access financial markets and smooth consumption fluctuations.     

Integration and arbitrage in the Spanish financial markets: An empirical approach*

Several authors have introduced different ways to measure integration between financial markets. Most of them are derived from the basic assumptions about asset prices, like the Law of One Price or the absence of arbitrage opportunities. Two perfectly integrated markets must give identical prices to identical final payoffs, and a vector of positive discount factors, common to both markets, must exist. If these properties do not hold, the degree to which they are violated can be defined and considered as a measure of integration. The present paper empirically tests integration measures in the Spanish financial markets. Furthermore, the integration measures are operationalized to analyze the presence of cross‐market arbitrage without previously specifying the exact nature of the arbitrage strategy to be used. When the absence of arbitrage holds, several interesting variables are obtained, for instance, state prices or risk‐neutral probabilities. When this absence fails, explicit cross‐market arbitrage portfolios are provided. The results of the test yield some evidence about market efficiency and integration outside the United States, and they are surprising for several reasons. First of all, arbitrage opportunities do sometimes appear, and the bid–ask spread and transaction costs seem to be unable to prevent arbitrage profits. Furthermore, the criticisms that are usually raised when empirical papers show the existence of arbitrage opportunities do not apply here because we work with perfectly synchronized high frequency data. On the other hand, different integration measures show a similar evolution along the tested period, although these measures give different information about the markets’ efficiency and integration, and they do not necessarily have to be related. © 2000 John Wiley & Sons, Inc.

Foreign shocks and international cost of equity destabilization. Evidence from the MENA region

This paper investigates whether foreign financial shocks can destabilize the cost of equity in emerging markets. After a theoretical discussion, we develop annual metrics for the international cost of equity, financial integration, spillovers and shift-contagion vulnerability in a sample of 535 Middle East and North African firms from Egypt, Tunisia, Morocco and Jordan over the 1998–2011 period. We then analyze the impact of foreign shocks on the international cost of equity, using a set of SGMM and PVAR models. Our results indicate that external shocks can increase the cost of equity in mature emerging markets.     

Regime Dependent Sensitivity of Country Exchange Traded Funds to Common Risk Factors

If common factors jointly affect country stock markets, it is an indication of global stock market integration. Common factors may affect some markets more/less than other markets, an indication of the degree of global stock market integration/ segmentation. In this paper, we study the integration of global stock markets based on the returns on exchange traded funds (ETFs) for the US, Canada, UK, Germany, France, Italy, Australia and Japan. The relationship between country ETF returns and common risk factors may be time-varying across countries, and that favors a regime switching (RS) factor model for the dynamics of the country ETF returns. A RS factor model for the relationship between country ETF returns and common risk factors is fitted to daily data for the period from May 31, 2000 to March 31, 2014. We use the data to test a hierarchy of hypotheses on country ETF returns: (1) common factor exposure across all country ETFs and all regimes; (2) common factor exposure across some country ETFs and all regimes, and (3) common factor exposure across some country ETFs and some regimes. The RS factor model for ETF returns fits the data well and the common factors have variable effects across countries and over regimes.     

On commodity price limits

This paper examines the behavior of futures prices and trader positions around the occurrence of price limits in commodity futures markets. We ask whether limit events are the result of shocks to fundamental volatility or the result of temporary volatility induced by the trading of noncommercial market participants (speculators). We find little evidence that limits events are the result of speculative activity, but instead associated with shocks to fundamentals that lead to persistent price changes. When futures trading halts price discovery migrates to options markets, but option prices provide a biased estimate of subsequent future prices when trading resumes.
