During the past three decades, many countries have lifted restrictions on cross-border financial transactions. We present a simple model that can account for the observed effects of financial globalization. The model emphasizes the role of imperfect enforcement of domestic debts and the interactions between domestic and foreign debts. Financial globalization can lead to a variety of outcomes: (i) domestic capital flight and ambiguous effects on net capital flows, investment, and growth; (ii) capital inflows and higher investment and growth; or (iii) volatile capital flows and unstable domestic financial markets. The model shows how the effects of financial globalization depend on the level of development, productivity, domestic savings, and the quality of institutions.

This paper synthesizes recent advances in the theoretical and empirical literature on capital controls. We start by observing that international capital flows have both benefits and costs, but some of these are not internalized by individual actors and thus constitute externalities. The theoretical literature has identified pecuniary externalities and aggregate demand externalities that respectively contribute to financial instability and recessions. These externalities provide a natural rationale for countercyclical capital controls that lean against boom and bust cycles in international capital flows. The empirical literature has developed several measures of capital controls to capture different aspects of capital account openness. We evaluate the strengths and weaknesses of different measures and provide an overview of the empirical findings on the effectiveness of capital controls in addressing the externalities identified by the theory literature, that is, in reducing financial fragility and enhancing macroeconomic stability. We also discuss strategies to deal with the endogeneity of capital controls in such statistical exercises. We conclude by providing an overview of the historical and current debates on the role of capital controls in macroeconomic management and their relationship to the academic literature.

This paper presents a new data set of capital controls by inflows and outflows for 10 asset categories in 100 countries during 1995-2013. Building on the data in Schindler (2009) and other data sets based on the analysis of the IMF's Annual Report on Exchange Arrangements and Exchange Restrictions (AREAER), this data set covers additional asset categories, more countries, and a longer time period. The paper discusses in detail the construction of the data and characterizes them with respect to the prevalence and correlation of controls across asset categories and between inflow and outflow controls, the aggregation of the separate categories into broader indicators, the experience of some particular countries, and the comparison of these data with others indices of capital controls.

We use the introduction of a financial transaction tax (FTT) in France in 2012 to test competing theories on its impact. We find no support for the idea that an FTT improves market quality by affecting the composition of trading volume. Instead, our results are in line with the hypothesis that a lower trading volume reduces liquidity and in turn market quality. Consistent with theories of asset pricing under transaction costs, we document a shift in security holdings from short-term to long-term investors. Finally, we find that moderate aggregate effects on market quality can mask large adjustments made by individual agents.

We study the effect of trading costs on information aggregation and acquisition in financial markets. For a given precision of investors' private information, an irrelevance result emerges when investors are ex ante identical: price informativeness is independent of the level of trading costs. When investors are ex ante heterogeneous, a change in trading costs can increase or decrease price informativeness, depending on the source of heterogeneity. Our results are valid under quadratic, linear, and fixed costs. Through a reduction in information acquisition, trading costs reduce price informativeness. We discuss how our results inform the policy debate on financial transaction taxes/Tobin taxes.

This paper examines the effect of financial sanctions on cross-border capital flows. While sanctions can be expected to hinder international transactions, thereby putting political and economic pressure on a target country, we study the patterns of adjustment in bilateral financial relationships after the imposition of sanctions along various dimensions. Our analysis is based on highly disaggregated, monthly data from the German balance of payments statistics for the period from 2005 through 2014. During this time, Germany imposed financial sanctions on 20 countries; two of these sanctions have been lifted. Applying a differences-in-differences approach, we find two key results. First, financial sanctions have a strong and immediate negative effect on direct financial flows with the sanctioned country, with cross-border flows reduced in either direction. Second, sanctions imposed by the European Union alone, and therefore only enforced by their member countries instead of the United Nations, are evaded as flows with major trading partners of sanctioned countries increase. We conclude that financial sanctions do matter for capital flows.

We explore issues related to a financial transaction tax (FTT) in the United States. We trace the history and current practice of the tax in the United States and other countries, review evidence of its impact on financial markets, and explore the key design issues any such tax must address. We present new revenue and distributional effects of a hypothetical relatively broad-based FTT in the United States, finding that, at a base rate of 0.34 percent, it could raise a maximum of about 0.4 percent of GDP ($75 billion in 2017) in a highly progressive manner.

Who writes the rules of global finance? This article explains how the transnational financial policy community can influence the content of financial governance by organizing itself via a club model. This agent-centered explanation advances the concept of a club to highlight the mechanisms through which actors operate, the expertise and skills valued by this community and the way in which principles for what constitutes appropriate financial governance are derived. Evidence is provided by an investigation of the Group of Thirty, part-think tank, part-advocacy group, a hybrid organization whose members are active in both the official and private sectors. Club characteristics can be seen in the group's high profile and prestigious membership, which self-presents a strong sense of honor. The article highlights the club as a location for those traditionally understood as financial elites. It emphasizes the collective attributes of the club, such as reputational consistency of membership, but also the importance of a track record of policy work for the enduring relevance of club arrangements in agenda-setting, consensus building and establishing mechanisms for private influence in financial governance. The study draws on 80+ interviews with key stakeholders from the community, including group members, conducted between 1998 and 2010.

This empirical study addresses the impact of securities transaction taxes (STTs) on price informativeness. Two specific events are assessed: the entry into force of STTs in France and Italy in 2012 and 2013, respectively. Specifically, it is gauged whether those events produced effects on the future earnings response coefficient (FERC)—a proxy for the capacity of investors to anticipate future earnings—of the stocks eligible for the STT. Our findings indicate that the new taxes on securities transactions that entered into force in France and Italy were neutral with respect to the effects on price informativeness. That is, no material changes in the FERC of affected stocks are detected in the aftermath of the STTs’ entry into force. This result applies when considering the events in France and Italy separately, and when analyzing different subsets of the sample based on the size, trading activity, and liquidity of the stocks.

This article performs a welfare analysis of markets with private information in which agents condition on prices in the rational expectations tradition. Price-contingent strategies introduce two externalities in the use of private information: a pecuniary externality and a learning externality. The pecuniary externality induces agents to put too much weight on private information and in the standard case, when the allocation role of the price prevails over its informational role, overwhelms the learning externality which impinges in the opposite way. The price may be very informative but at the cost of an excessive dispersion of the actions of agents. The welfare loss at the market solution may be increasing in the precision of private information. The analysis provides insights into optimal business cycle policy and a rationale for a Tobin-like tax for financial transactions.
