How Should Shale Gas Extraction Be Taxed?
Description: This paper suggests that the environmental and commercial features of shale gas extraction do not warrant a significantly different fiscal regime than recommended for conventional gas. Fiscal policies may have a role in addressing some environmental risks (e.g., greenhouse gases, scarce water, local air pollution) though in some cases their net benefits may be modest. Simulation analyses suggest, moreover, that special fiscal regimes are generally less important than other factors in determining shale gas investments (hence there appears little need for them), yet they forego significant revenues.

Taxing Telecommunications in Developing Countries
Description: Developing countries apply numerous sector-specific taxes to telecommunications, whose buoyant revenues and formal enterprises provide a convenient “tax handle”. This paper explores whether there is an economic rationale for sector-specific taxes on telecommunications and, if so, what form they should take to balance the competing goals of promoting connectivity and mobilizing revenues. A survey of the literature finds that limited telecoms competition likely creates rents that could efficiently be taxed. We propose a “pecking order” of sector-specific taxes that could be levied in addition to standard income and value-added taxes, based on capturing rents and minimizing distortions. Taxes that target possible economic rents or profits are preferable, but their administrative challenges may necessitate reliance on service excises at the cost of higher consumer prices and lower connectivity. Taxes on capital inputs and consumer access, which distort production and restrict network access, should be avoided; so should tax incentives, which are not needed to attract foreign capital to tap a local market.

Assessing Loss of Market Access: Conceptual and Operational Issues
Description: Loss of market access (LMA) is a central element and an exacerbator of balance of payments and fiscal crises. This paper provides an operational definition of LMA, examines the predictive power of potential LMA leading indicators, attempts to determine the likely nature (temporary versus structural) of an LMA episode, and analyzes potential implications of such an assessment on the required degree of adjustment to restore market access. Finally, it highlights the possible application of the methodological framework for identifying emerging risks to market access.

Basel III and Bank-Lending: Evidence from the United States and Europe
Description: Using data on commercial banks in the United States and Europe, this paper analyses the impact of the new Basel III capital and liquidity regulation on bank-lending following the 2008 financial crisis. We find that U.S. banks reinforce their risk absorption capacities when expanding their credit activities. Capital ratios have significant, negative impacts on bank-retail-and-other-lending-growth for large European banks in the context of deleveraging and the “credit crunch” in Europe over the post-2008 financial crisis period. Additionally, liquidity indicators have positive but perverse effects on bank-lending-growth, which supports the need to consider heterogeneous banks’ characteristics and behaviors when implementing new regulatory policies.

Hollowing Out: The Channels of Income Polarization in the United States
Description: Data show that middle-income households have continued moving down, and less so up, the income distribution in the United States since the 1970s—a phenomenon that is often referred to as the polarization or “hollowing out” of the income distribution. While the level of income polarization is generally lower in the richer states (i.e., those with higher median household income levels), there have been wide variations in the changes in income polarization over time across states. The paper develops two indices to measure income polarization including a novel hollowing-out index. Another important contribution of the paper is to examine the proximate causes of income polarization. The econometric analysis is done at both state and household levels. The results suggest that technology, measured by job routinization, and international trade, measured by job offshoring, can fully explain the non-trend rise in income polarization, with broadly equal contributions. Household characteristics, including age, education, race, and gender have also been important drivers but with a net countervailing effect on income polarization. This is mainly thanks to the rising education level of households, which has led to better incomes.

Enforcing Public-Private Partnership Contract: How do Fiscal Institutions Matter?
Description: Public-private partnerships (PPPs) have increased rapidly in emerging and developing countries, creating both opportunities and fiscal challenges. One of the main challenges is that while governments have increased commitments in guarantees and direct subsidies to promote PPPs, contractual disputes remain high with significant costs. This paper examines how fiscal institutions affect the selection of PPP contracts and the probability of contract disputes using about 6,000 PPP contract-level data. The analysis shows that larger government financing needs, lower budget transparency and bureaucratic efficiency are associated with higher probability for governments to offer guarantees. Propensity score matching results show that disputes are more common for guaranteed contracts due to adverse selection and contingent liability effects. PPP management quality and budget transparency are found to be key determinants for a longer survival of PPPs.

The Slowdown in Global Trade: A Symptom of A Weak Recovery
Description: Global trade growth has slowed since 2012 relative both to its strong historical performance and to overall economic growth. This paper aims to quantify the role of weak economic growth and changes in its decomposition in accounting for the slowdown in trade using a reduced form and a structural approach. Both analytical investigations suggest that the overall weakness in economic activity, particularly investment, has been the primary restraint on trade growth, accounting for over 80 percent of the decline in the growth of the volume of goods trade between 2012–16 and 2003–07. However, other factors are also weighing on trade in recent years, especially in emerging market and developing economies, as evidenced by the non-negligible role attributed to trade costs by the structural approach.

Fiscal Spillovers in the Euro Area: Letting the Data Speak
Description: We estimate a panel VAR model that captures cross-country, dynamic interlinkages for 10 euro area countries using quarterly data for the period 1999-2016. Our analysis suggests that fiscal spillovers are significant and tend to be larger for countries with close trade and financial links as well, as for fiscal shocks originating from larger countries. The current account appears to be the main channel of transmission, although strong trade integration among countries in the euro area and spillback effects tend to zero-out the net trade impact in some cases. A subsample analysis shows that the effects of fiscal policy have changed over time, with larger estimated domestic multipliers and spillovers between 2011 and 2014.

Fear Thy Neighbor: Spillovers from Economic Policy Uncertainty
Description: High levels of economic policy uncertainty in various parts of the world revamped the de- bate about its impact on economic activity. With increasingly stronger economic, fi nancial, and political ties among countries, economic agents have more reasons to be vigilant of for- eign economic policy. Employing heterogeneous panel structural vector autoregressions, this paper tests for spillovers from economic policy uncertainty on other countries' economic ac- tivity. Furthermore, using local projections, the paper zooms in on shocks originating in the United States, Europe, and China. Our results suggest that economic policy uncertainty re- duces growth in real output, private consumption, and private investment, and that spillovers from abroad account for about two-thirds of the negative effect. Moreover, uncertainty in the United States, Europe, and China reduces economic activity in the rest of the world, with the effects being mostly felt in Europe and the Western Hemisphere.

Unconventional Policies and Exchange Rate Dynamics
Description: We study exchange rate dynamics under cooperative and self-oriented policies in a two-country DSGE model with unconventional monetary and exchange rate policies. The cooperative solution features a large exchange rate adjustment that cushions the impact of negative shocks and a moderate use of unconventional policy instruments. Self-oriented policies (Nash equilibrium), however, entail limited exchange rate movements and an aggressive use of unconventional policies in both countries. Our results highlight the role of international policy cooperation in allowing the exchange rate to play the traditional role of shock absorber.
