We review the literature on the empirical characteristics of the global financial cycle and associated stylized facts on international capital flows, asset prices, risk aversion and liquidity in the financial system. We analyse the co-movements of global factors in asset prices and capital flows with commodity prices, international trade and world output as well as the sensitivity of different parts of the world to the Global Financial Cycle. We present evidence of the causal effects of the monetary policies of the US Federal Reserve, the European Central Bank and of the People's Bank of China on the Global Financial Cycle. We then assess whether the 2008 financial crisis has altered the transmission channels of monetary policies on the Global Financial Cycle. Finally, we discuss the theoretical modelling of the Global Financial Cycle and avenues for future research.
Financial crises have large deleterious effects on economic activity, and as such have been the focus of a large body of research. This study surveys the existing literature on financial crises, exploring how crises are measured, whether they are predictable, and why they are associated with economic contractions. Historical narrative techniques continue to form the backbone for measuring crises, but there have been exciting developments in using quantitative data as well. Crises are predictable with growth in credit and elevated asset prices playing an especially important role; recent research points convincingly to the importance of behavioral biases in explaining such predictability. The negative consequences of a crisis are due to both the crisis itself but also to the imbalances that precede a crisis. Crises do not occur randomly, and, as a result, an understanding of financial crises requires an investigation into the booms that precede them.
This paper employs an updated algorithm and database for classifying exchange rate and anchor currency choice, to explore the evolution of the global exchange rate system, including parallel rates, capital controls and reserves. In line with a large recent literature, we find that the dollar has become ever-more central as the de facto anchor or reference currencies for much of the world. Our discussion encompasses the history of anchor currency choice, methods for classifying exchange rate regimes, a detailed discussion of the evolution of regimes, the growing substitution of reserves for capital controls as a tool for exchange rate stabilization, the modern Triffin dilemma, and the surprising recent trend decline in volatility of exchange rates at the core of the system. It concludes with issues surrounding the rise of China.
We provide a simple framework to study the prudential use of capital controls and currency reserves that have been explored in the recent literature. We cover the role of both pecuniary externalities and aggregate demand externalities. The model features a central policy dilemma for emerging economies facing large capital outflows: the choice between increasing the policy rate to stabilize the exchange rate and decreasing the policy rate to stabilize employment. Ex ante capital controls and reserve accumulation can help mitigate this dilemma. We use our framework to survey the recent literature and provide an overview of recent empirical findings on the use of these policies.
How should international economic policy address climate change? Does trade cause deforestation and endangered species depletion? How does globalization affect air and water pollution? Do trade and investment create a race to the bottom in environmental policy? How important are environmental impacts of transporting goods? We review theory and empirical work linking international trade and the environment with a focus on recent work and methods. We discuss the literature linking trade to local and global pollutants, the impact of emissions from transportation, the effect of trade on the sustainability of renewable resources, and the interaction between trade and climate policy. To shape our review, we present nine new stylized facts that, together with our review of past work, highlight questions for future research.Institutional subscribers to the NBER working paper series, and residents of developing countries may download this paper without additional charge at www.nber.org.
We review the literature on the globalization backlash, seen as the political shift of voters and parties in a protectionist and isolationist direction, with substantive implications on governments’ leaning and enacted policies. Using newly assembled data for 23 advanced democracies, we document a protectionist and isolationist shift in electorates, legislatures, and executives from the mid-1990s onwards. This is associated with a noticeable protectionist shift in trade policy –although with some notable nuances– especially since the financial crisis of 2008. We discuss the economics of the backlash. From a theoretical perspective, we highlight how the backlash may arise within standard trade models when taking into account the ‘social footprint’ of globalization. Then, we review the empirical literature on the drivers of the backlash. Two main messages emerge from our analysis: (1) globalization is a significant driver of the backlash, by means of the distributional consequences entailed by rising trade exposure; yet (2) the backlash is only partly determined by trade. Technological change, crisis-driven fiscal austerity, immigration, and cultural concerns are found to play an important role in creating politically consequential cleavages. Looking ahead, we discuss possible future developments, with specific focus on the issue of social mobility.
This chapter was prepared for the Handbook of International Economics (Vol. 5) edited by Gita Gopinath, Elhanan Helpman, and Kenneth Rogoff. We provide a review of the recent literature --both theoretical and empirical -- analyzing the multi-dimensional connections between globalization and innovation. We develop a model that features many of those mechanisms that connect trade and innovation. It features the joint selection of firms into innovation and international market participation (in our model, we restrict that participation to exports). Our model also highlights how exposure to international markets affects the incentives for innovation.
A review of recent advances in open economy analysis under segmented international financial markets. A set of modeling tools that have been used to understand ?financialcrises, the ensuing policy response (e.g., Quantitative Easing and FX intervention), deviations from arbitrage (CIP deviations), and more generally the impact of capital flows on exchange rates. This modeling approach has also sheds a different light onclassic topics such as the exchange rate disconnect, international risk sharing, UIPfailures, and the carry trade.
This paper reviews recent research on geography and trade. One of the key empirical findings over the last decade has been the role of geography in shaping the distributional consequences of trade. One of the major theoretical advances has been the development of quantitative spatial models that incorporate both exogenous first-nature geography (natural endowments) and endogenous second-nature geography (the location choices of economic agents relative to one another) as determinants of the distribution of economic activity across space. These models are sufficiently rich to capture first-order features of the data, such as gravity equations for flows of goods and people. Yet they remain sufficiently tractable as to permit an analytical characterization of the properties of the general equilibrium and facilitate counterfactuals for realistic policy interventions. We distinguish between models of regions or systems of cities (where goods trade and migration take center stage) and models of the internal structure of cities (where commuting becomes relevant). We review some of key empirical predictions of both sets of theories and show that they have been remarkably successful in rationalizing the empirical findings from reduced-form research. Looking ahead, the combination of recent theoretical advances and novel geo-coded data on economic interactions at a fine spatial scale promises many interesting avenues for further research, including discriminating between alternative mechanisms for agglomeration, understanding the implications of new technologies for the organization of work, and assessing the causes, consequences, and potential policy implications of spatial sorting.
A handful of currencies, especially the US dollar, play a dominant role in international trade.We survey the active theoretical and empirical literature that documents patterns of currency use in global trade, the implications of dominant currencies for international transmission of shocks, exchange rate pass-through, expenditure switching, and optimal monetary policy.We describe advances in the endogenous currency choice literature including conditions for the emergence and persistence of dominant currency equilibria.
This chapter develops a framework with which to interpret and survey answers to the question: how does increased openness affect aggregate welfare in a typical developing country? We decompose answers into four mechanisms: (i) an effect akin to technological progress that is purely mechanical; (ii) an effect on factoral terms of trade; (iii) a distortion revenue effect that exacerbates or mitigates the consequences of domestic distortions; and (iv) an effect of trade on the magnitude of those distortions themselves. Our focus lies in the last two mechanisms as these are especially important for the study of low-income settings where domestic distortions are thought to be rife. Throughout, we provide both a review of existing work on these topics and quantitative calculations that aim to gauge the magnitudes involved in a global model that is calibrated to match firm- and industry-level data on trade flows, production techniques, and a host of distortions (tariffs, other taxes, markups, bribes, theft, credit constraints, contracting failures, labor regulations, and public utility provision) that have featured in the literature.
This paper surveys the recent body of work in economics on the importance of global value chains (GVCs) in shaping international trade flows and multinational activity. On the empirical front, we begin reviewing several variants of the macro approach to measuring the relevance of global production sharing in the world economy, and we also offer a critical evaluation of the country- and industry-level datasets (or World Input Output Tables) that have been used to date. We next discuss the advantages and disadvantages of a burgeoning alternative micro approach that has instead employed firm-level datasets to document the ways in which firms have sliced up their value chains across countries. On the theoretical front, we propose an analogous dissection of the literature. First, we review a vast body of work developing country- and industry-level quantitative frameworks that are easily calibrated with World Input Output Tables, and that open the door for counterfactual exercises with minimal demands on estimation. Second, we overview micro-level frameworks that have treated firms rather than countries or industries as the relevant unit of analysis, and that have unveiled a number of distinctive mechanisms by which GVCs shape the determinants and consequences of international trade flows in ways distinct from traditional models of international trade. We close this survey with a discussion of a still infant literature on the desirability and effects of trade policy in a world of GVCs.

The covered interest rate parity (CIP) condition is a fundamental arbitrage relationship in international finance. In this chapter, we review its breakdown during the Global Financial Crisis and its continued failure in the subsequent decade. We review how to measure CIP deviations, discuss the drivers of CIP deviations, and the implications of CIP deviations for global financial markets.
In this chapter, we use a benchmark limited-commitment model to explore key issues in the economics of sovereign debt. After highlighting conceptual issues that distinguish sovereign debt as well as reviewing a number of empirical facts, we use the model to discuss debt overhang, risk-sharing, and capital flows in an environment of limited enforcement. We also discuss recent progress on default and renegotiation; self-fulfilling debt crises; and incomplete markets and their quantitative implications. We conclude with a brief assessment of the current state of the literature and highlight some directions for future research.
We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. Wehighlight how various economic considerations-market structure, firm-level heterogeneity, multiple sectors, intermediate goods, and multiple factors of production-affect the magnitude of the gains from trade liberalization. We conclude by discussing a number of outstanding issues in the literature as well as alternative approaches for quantifying the consequences of globalization.
This chapter is structured in three parts. The first part outlines the methodological steps, involving both theoretical and empirical work, for assessing whether an observed allocation of resources across countries is efficient. The second part applies the methodology to the long-run allocation of capital and consumption in a large cross section of countries. We find that countries that grow faster in the long run also tend to save more both domestically and internationally. These facts suggest that either the long-run allocation of resources across countries is inefficient, or that there is a systematic relation between fast growth and preference for delayed consumption. The third part applies the methodology to the allocation of resources across developed countries at the business cycle frequency. Here we discuss how evidence on international quantity comovement, exchange rates, asset prices, and international portfolio holdings can be used to assess efficiency. Overall, quantities and portfolios appear consistent with efficiency, while evidence from prices is difficult to interpret using standard models. The welfare costs associated with an inefficient allocation of resources over the business cycle can be significant if shocks to relative country permanent income are large. In those cases partial financial liberalization can lower welfare.
This chapter surveys recent research on international financial crises. A financial crisis is characterized by a sudden, dramatic outflow of financial resources from an economy with an open capital account. This outflow may be primarily driven by the expectation of a large nominal devaluation, in a situation in which the domestic monetary-fiscal regime appears inconsistent with a fixed exchange rate. Or the outflow may be driven by a reallocation of funds by foreign and domestic investors, due to a changed perception in the country's growth prospects, to an increase in the risk of domestic default, or to a shift in investors' attitudes toward risk. Often times, monetary and financial elements are combined. A drop in domestic asset prices and in the real exchange rate can act as powerful amplifiers of the real effects of the crisis, through adverse balance-sheet adjustments. The chapter surveys research that looks both at the monetary and at the financial side of crises, also discussing work that investigates the accumulation of imbalances preceding the crisis and the scope for preventive policies.
We provide an overview of the recent developments of the literature on the determinants of long-term capital flows, global imbalances, and valuation effects. We present the main stylized facts of the new international financial landscape in which external balance sheets of countries have grown in size and discuss implications for the international monetary and financial system.
