Abstract:
It is well-known that exchange rates are difficult to forecast using observed macro-fundamental variables. This discrepancy between economic theory and empirical results is called the Meese and Rogoff puzzle. The purpose of this study is to address this puzzle from a new approach. Rather than pursuing a linkage between macro-fundamentals and exchange rates, we focus on the market sentiment index as a factor that could possibly enhance exchange rate predictability. The analysis folds into three phases. First, we conducted an assessment of the traditional exchange rate predictability model, as well as the augmented traditional model incorporating the market sentiment index. Second, we predicted the exchange rate by applying the market sentiment index, based on the contrarian opinion investment strategy commonly used by foreign exchange dealers. Finally, we analyzed if the machine learning model incorporating both economic fundamentals and market sentiment index could enhance the predictability of the exchange rate.

22. Boom-bust Cycles Revisited: The Role of Credit Supply

Author:
Hyo Sang Kim, Sangyup Choi, and Yuri Kim
Publication Date:

Content Type:
Policy Brief
Institution:
Korea Institute for International Economic Policy (KIEP)
Abstract:
This study investigates the impacts of credit supply on economic growth and financial crisis. Excess credit supply can make the economy and financial markets more vulnerable. While credit supply can drive economic growth by reallocating resources, it can also make the economy and financial markets more fragile. Asset prices sharply fall when deleveraging occurs in the case of a negative shock to the financial or real sector in a system where credit is excessively supplied. Furthermore, economic activity might be substantially reduced, extending the length and breadth of the recession.

23. The international financial system after COVID-19

Working Paper

Peterson Institute for International Economics (PIIE)
Abstract:
In March 2020, international markets seized up with a violence unequaled since the global financial crisis nearly a dozen years before. As economies around the world locked down in the face of the potentially deadly but completely novel SARS-CoV-2 virus, stock markets fell, firms and governments scrambled for cash, liquidity strains emerged even in the market for US Treasurys, and capital flows to emerging-market and developing economies (EMDEs) reversed violently. This paper reviews the evolution of global financial markets since the global financial crisis, changes in academic thinking about these markets’ domestic impacts, the strains seen during the COVID-19 crisis, and perils that may lie ahead. A key theme is that stability will be enhanced if the global community embraces reforms that elevate market resilience, rather than depending on skillful policymakers wielding aggressive but ad hoc policy interventions to ride to the rescue again.

24. WTO 2025: Enhancing global trade intelligence

Author:
Alan Wm. Wolff
Publication Date:

Content Type:
Working Paper
Institution:
Peterson Institute for International Economics (PIIE)
Abstract:
International trade flows based on information. Is the foreign market open? What are the conditions for entry? Are there customs duties to be paid and other regulations that need to be satisfied? Businesses thrive on getting as much certainty as they can find, and this requires reliable information. Is the competition subsidized? Are the competitors favored state-owned companies? During the pandemic, governments needed to know if food and medical supplies were going to be available from foreign sources and, most importantly, how available vaccines would be as most of the world’s countries could not produce any. Effective public policy cannot be made in the dark. The World Trade Organization, and the General Agreement on Tariffs and Trade before it, were founded with the idea of providing transparency. But more is needed to understand why trade is taking place, and even more important, when it is not, why not?

25. Slippery Fish: Enforcing Regulation under Subversive Adaptation

Author:
Andres Gonzalez-Lira
Publication Date:
04-2022
Content Type:
Policy Brief
Institution:
The Cato Institute
Abstract:
Correcting market failures and improving economic efficiency often require curbing undesirable behaviors of market agents who act to maximize their private benefits. Examples include actions that affect ecosystems, such as deforestation, pollution, and overexploitation of natural resources; actions that affect community health, such as drunk driving and open defecation; or actions that undermine government performance, such as corruption and tax evasion. Enacting and enforcing regulations is the most direct strategy to deter such behaviors. Implementing this strategy requires strong institutions to enforce laws, plus sophisticated policing to track agents’ reactions to enforcement so that rules are robust enough to curb the undesirable behavior even when regulated agents try to game the new system.

26. A Gravity Theory of Subordinate Financialisation

Author:

Abstract:
Recent decades have marked both the globalisation of capitalism following the collapse of communism and its financialisation following the rapid growth of the world's securities markets. These developments have impacted the core-periphery divide in capitalism. In the case of globalisation, the entry of the ex-communist countries into the world capitalist system has swelled the ranks of the emerging capitalist economies (ECEs) that are kept subordinate through the pressures from the advanced capitalist economies (ACEs). In the case of financialisation, the growth of the securities markets has led to a palpable change in the pressures that perpetuate subordination. Where previously the use of authority was the chief source of those pressures, it now plays a secondary role. Absent that authority, and the ECEs would still be held in a subordinate position in global capitalism through the gravitational pull of the ACEs' financial securities markets. The central purpose of this paper is to explain this gravitational pull.

27. Yet it Endures: The Persistence of Original Sin

Abstract:
Notwithstanding announcements of progress, "international original sin" (the denomination of external debt in foreign currency) remains a persistent phenomenon in emerging markets. Although some middle-income countries have succeeded in developing markets in local-currency sovereign debt and attracting foreign investors, they continue to hedge their currency exposures through transactions with local pension funds and other resident investors. The result is to shift the locus of currency mismatches within emerging economies but not to eliminate them. Other countries have limited original sin by limiting external borrowing, passing up valuable investment opportunities in pursuit of stability. We document these trends, analyzing regional and global aggregates and national case studies. Our conclusion is that there remains a case for an international initiative to address currency risk in low- and middle-income economies so they can more fully exploit economic development opportunities.

28. Economic Effects of FDI: How Important is Rising Market Concentration?

Author:
Kasper Vrolijk

Content Type:
Policy Brief

Abstract:
Many governments adopt policies and actively compete to attract foreign direct investment (FDI). Particularly for lower-income countries, attracting FDI – and with it the benefits of cooperating with multi-national enterprises (MNEs) – is a promising strategy for participating in global supply chains and increasing local firm productivity. However, empirical findings show contrasting effects and there is heated debate over FDI’s advantages and drawbacks. The current trend to rising market concentration also begs the question: Have FDI effects changed in recent years? This Policy Brief aims to address these questions by studying FDI and what the apparent growth in market concentration implies. Although foreign investment theoretically raises productivity, creates employment and offers many other benefits, the empirical evidence is not unequivocal. Initial coarse country-level data found that receptivity to FDI raises the host country’s economic growth. But later research used more detailed sector data and showed ambiguous effects (Görg & Greenaway, 2004). New microdata confirm that FDI effects are differential: Not all workers and households benefit equally. They also showcase the different ways in which MNEs and FDI benefit firms, workers and households in host countries. Recently, superstar firms, which capture large shares of industries and thereby increase market con-centration, have emerged. Linked to reduced national economic dynamism and evident in global markets, the rise of superstar firms could negatively impact on FDI effects. They differ from MNE competition effects and confer market power so that MNEs can determine prices and wages. This trend toward rising market concentration is observed across multiple sectors and has several possible causes, such as technological and legal factors. A literature survey reveals a lack of evidence about how rising concentration in global markets is affecting FDI gains. However, other evidence suggests that the positive spillovers to domestic firms may well be lower, with higher market concentration negatively affecting wages and employment. The following takeaways can be derived for policy-making: 1. Integrate competition policy: Competition effects should be considered when evaluating FDI and policies should be introduced to ensure competitive practises after FDI entry. 2. Improve monitoring: Collect data on competi-tive forces and how they change when MNEs enter host economies. 3. Absorb regressive effects: Introduce social benefits to counter the potential mixed effects of FDI and MNE market power.

29. Platform mergers and antitrust

Author:

Publication Date:

Content Type:
Working Paper
Institution:
Bruegel
Abstract:
Platform ecosystems rely on economies of scale, data-driven economies of scope, high quality algorithmic systems, and strong network effects that frequently promote winner-takes-most markets. Some platform firms have grown rapidly and their merger and acquisition strategies have been very important factors in their growth. Big platforms’ market dominance has generated competition concerns that are difficult to assess with current merger policy tools. We examine the acquisition strategies of the five major US firms—Google, Amazon, Facebook, Apple and Microsoft—since their inception. We discuss the main merger and acquisition theories of harm that can restrict market competition and reduce consumer welfare. To address competition concerns about acquisitions in big platform ecosystems we develop a four step proposal that incorporates: (1) a new ex-ante regulatory framework, (2) an update of the conditions under which the notification of mergers should be compulsory and the burden of proof should be reversed, (3) differential regulatory priorities in investigating horizontal versus vertical acquisitions, and (4) an update of competition enforcement tools to increase visibility into market data and trends.
