Late to the game? Capital flows to the Western Balkans
Description: The boom and bust in capital flows to the New Member States of the European Union have received a considerable amount of attention; foreign direct investment and bank flows to the region and countries’ participation in regional supply chains have been well-documented. Relatively little has, however, been written about capital flows to the Western Balkans economies, which are often perceived to be ‘late arrivals’ to large capital flows. This paper aims to examine how capital flows to the Western Balkans compare with flows to the New Member States, in terms of levels as well as dynamics. We find that while financial integration took off somewhat later in the Western Balkans than in the New Member States, it has increased rapidly, despite still much lower capital account openness. Capital inflows as a share of GDP are comparable to those observed in the New Member States, (perhaps surprisingly) diverse in terms of source countries and broadly similar in composition, though with equity shares higher than they were in the New Member States at comparable levels of GDP per capita.

Thick vs. Thin-Skinned: Technology, News, and Financial Market Reaction
Description: We study the impact of technology on the reaction of financial markets to information, focusing on the foreign exchange market. We contrast the “thin-skinned” view that technological improvements cause markets to react more to new information with the “thick-skinned” view that they react less. We pinpoint exogenous technological changes using the timing of the connection of countries via the submarine fiber-optic cables used for electronic trading. Cable connections dampen the response of exchange rates to macroeconomic news, consistent with the “thick-skinned” hypothesis. This is in line with the view that technology eases access to information and reduces trend-following behavior. According to our estimates, cable connections reduce the reaction of exchange rates to U.S. monetary policy news by 50 to 80 percent.

Policy, Risk and Spillover Analysis in the World Economy: A Panel Dynamic Stochastic General Equilibrium Approach
Description: This paper develops a structural macroeconometric model of the world economy, disaggregated into forty national economies, to facilitate multilaterally consistent macrofinancial policy, risk and spillover analysis. This panel dynamic stochastic general equilibrium model features a range of nominal and real rigidities, extensive macrofinancial linkages, and diverse spillover transmission channels. These macrofinancial linkages encompass bank and capital market based financial intermediation, with financial accelerator mechanisms linked to the values of the housing and physical capital stocks. A variety of monetary policy analysis, fiscal policy analysis, macroprudential policy analysis, spillover analysis, and forecasting applications of the estimated model are demonstrated. These include quantifying the monetary, fiscal and macroprudential transmission mechanisms, accounting for business cycle fluctuations, and generating relatively accurate forecasts of inflation and output growth.

Tax Administration Reforms in the Caribbean: Challenges, Achievements, and Next Steps
Description: Over the past decade, governments in the Caribbean region have introduced the value-added tax (VAT) to modernize their tax system, rapidly mobilize revenue and reduce budget deficits. This paper analyzes VAT performance in the region and concludes that while it has boosted revenues, the VAT has not reached its potential. Intended as a broad-based tax with limited exemptions, a single rate and zero-rating confined to exports, the VAT’s design often lacks these characteristics. The paper also finds that although tax administration reforms can boost revenues, countries have just started to address organizational inefficiencies, data integrity issues, and operational ineffectiveness. These reforms need to intensify in order to have a more significant impact on compliance and revenue.

Labor Market Institutions and the Cost of Recessions
Description: This paper studies the effect of two labor market institutions, unemployment insurance (UI) and job search assistance (JSA), on the output cost and welfare cost of recessions. The paper develops a tractable incomplete-market model with search unemployment, skill depreciation during unemployment, and idiosyncratic as well as aggregate labor market risk. The theoretical analysis shows that an increase in JSA and a reduction in UI reduce the output cost of recessions by making the labor market more fluid along the job finding margin and thus making the economy more resilient to macroeconomic shocks. In contarst, the effect of JSA and UI on the welfare cost of recessions is in general ambiguous. The paper also provides a quantitative appliation to the German labor market reforms of 2003-2005, the so-called Hartz reforms, which improved JSA (Hartz III reform) and reduced UI (Hartz IV reform). According to the baseline calibration, the two labor market reforms led to a substantial reduction in the output cost of recessions and a moderate reduction in the welfare cost of recessions in Germany.

Fiscal Crises
Description: A key objective of fiscal policy is to maintain the sustainability of public finances and avoid crises. Remarkably, there is very limited analysis on fiscal crises. This paper presents a new database of fiscal crises covering different country groups, including low-income developing countries (LIDCs) that have been mostly ignored in the past. Countries faced on average two crises since 1970, with the highest frequency in LIDCs and lowest in advanced economies. The data sheds some light on policies and economic dynamics around crises. LIDCs, which are usually seen as more vulnerable to shocks, appear to suffer the least in crisis periods. Surprisingly, advanced economies face greater turbulence (growth declines sharply in the first two years of the crisis), with half of them experiencing economic contractions. Fiscal policy is usually procyclical as countries curtail expenditure growth when economic activity weakens. We also find that the decline in economic growth is magnified if accompanied by a financial crisis.

Should Unconventional Monetary Policies Become Conventional?
Description: The large recession that followed the Global Financial Crisis of 2008-09 triggered unprecedented monetary policy easing around the world. Most central banks in advanced economies deployed new instruments to affect credit conditions and to provide liquidity at a large scale after shortterm policy rates reached their effective lower bound. In this paper, we study if this new set of tools, commonly labeled as unconventional monetary policies (UMP), should still be used when economic conditions and interest rates normalize. In particular, we study the optimality of asset purchase programs by using an estimated non-linear DSGE model with a banking sector and long-term private and public debt for the United States. We find that the benefits of using such UMP in normal times are substantial, equivalent to 1.45 percent of consumption. However, the benefits from using UMP are shock-dependent and mostly arise when the economy is hit by financial shocks. When more traditional business cycle shocks (such as supply and demand shocks) hit the economy, the benefits of using UMP are negligible or zero.

Effectiveness of Fiscal Incentives for R&D: Quasi-Experimental Evidence
Description: With growing academic and policy interest in research and development (R&D) tax incentives, the question about their effectiveness has become ever more relevant. In the absence of an exogenous policy reform, the simultaneous determination of companies’ tax positions and their R&D spending causes an identification problem in evaluating tax incentives. To overcome this identification challenge, we exploit a U.K. policy reform and use the population of corporation tax records that provide precise information on the amount of firm-level R&D expenditure. Using difference-in-differences and other panel regression approaches, we find a positive and significant impact of tax incentives on R&D spending, and an implied user cost elasticity estimate of around -1.6. This translates to more than a pound in additional private R&D for each pound foregone in corporation tax revenue.

Exchange Rate Regimes in Central, Eastern and Southeastern Europe: A Euro Bloc and a Dollar Bloc?
Description: There are 13 countries in Central, Eastern and Southeastern Europe (CESEE) with floating exchange rate regimes, de jure. This paper uses the framework pioneered by Frankel and Wei (1994) and extended in Frankel and Wei (2008) to show that most of them have been tracking either the euro or the US dollar in recent years. Eight countries, all of them current or aspiring EU members, track the euro. Of the five countries keying on the US dollar in various degrees, all but one belong to the Commonwealth of Independent States. The paper shows that the extent to which each country’s currency tracks the euro (or the dollar) is correlated with the structure of its external trade and finance. However, some countries appear to track the EUR or USD to an extent which appears inconsistent with inflation targeting, trade or financial integration, or the extent of business cycle synchronization. The phenomenon is particularly pronounced among the countries in the CESEE euro bloc, which may be deliberately gravitating around the euro in anticipation of eventually joining the Euro Area.

Optimal Fiscal and Monetary Policy, Debt Crisis and Management
Description: The initial government debt-to-GDP ratio and the government’s commitment play a pivotal role in determining the welfare-optimal speed of fiscal consolidation in the management of a debt crisis. Under commitment, for low or moderate initial government debt-to-GPD ratios, the optimal consolidation is very slow. A faster pace is optimal when the economy starts from a high level of public debt implying high sovereign risk premia, unless these are suppressed via a bailout by official creditors. Under discretion, the cost of not being able to commit is reflected into a quick consolidation of government debt. Simple monetary-fiscal rules with passive fiscal policy, designed for an environment with “normal shocks”, perform reasonably well in mimicking the Ramsey-optimal response to one-off government debt shocks. When the government can issue also long-term bonds–under commitment–the optimal debt consolidation pace is slower than in the case of short-term bonds only, and entails an increase in the ratio between long and short-term bonds.
