Rapid Current Account Adjustments: Are Microstates Different?
Description: We describe unique aspects of microstates-they are less diversified, suffer from lumpiness of investment, they are geographically at the periphery and prone to natural disasters, and have less access to capital markets-that may make the current account more vulnerable, penalizing exports and making imports dearer. After reviewing the "old" and "new" view on current account deficits, we attempt to identify policies to help reduce the current account. Probit regressions suggest that microstates are more likely to have large current account adjustments if (i) they are already running large current account deficits; (ii) they run budget surpluses; (iii) the terms of trade improve; (iv) they are less open; and (v) GDP growth declines. Monetary policy, financial development, per capita GDP, and the de jure exchange rate classification matter less. However, changes in the real effective exchange rate do not help drive reductions in the current account deficit in microstates. We explore reasons for this and provide policy implications.

Bank Losses, Monetary Policy and Financial Stability—Evidence on the Interplay from Panel Data
Description: We assess the extent to which loan losses affect banks’ provision of credit to companies and households and examine how feedback from losses to a reduction in credit is affected by the monetary policy stance. Using a unique cross-country dataset of more than 600 banks from 32 countries, we find that losses lead to a reduction in credit and that this effect is more pronounced when either initial bank capitalization is thin or when monetary policy is tight. Moreover, in the face of credit losses, ample capital is more important in cushioning the effect of loan losses when monetary policy is tight. In other words, capital buffers and accommodating monetary policy act as substitutes in offsetting the adverse effect of losses on loan growth. While most of these effects are stronger in crisis times, we find them to operate both in and outside full-blown banking crises. These findings have important implications for the interplay between financial stability and monetary policy, which this paper also draws out.

Tax Reforms, “Free Lunches”, and “Cheap Lunches” in Open Economies
Description: This paper focuses on the macroeconomic and budgetary impact of tax reforms in a New Keynesian two-country model. Our results show that both income and consumption unilateral tax rate reductions do not constitute a "free lunch", in the sense that they have negative budgetary consequences for the country which implements them. In addition, the degree of self-financing implied by our model is in the 8½-24 percent range. Since the degree of self-financing estimated in previous literature was larger, we conclude that in our model not only the "lunch" is not "free", but is also not that "cheap". A comparison of alternative (income-tax versus consumption-tax based) fiscal stimulus packages shows that consumption tax cuts imply a larger short-run impact on domestic output but the income tax cuts stimulate the domestic economy more in the long run. We also look at the implications of a revenue-neutral tax reform in which consumption taxes are increased to compensate for lower income tax collection.

An Anatomy of Credit Booms: Evidence From Macro Aggregates and Micro Data
Description: We study the characteristics of credit booms in emerging and industrial economies. Macro data show a systematic relationship between credit booms and economic expansions, rising asset prices, real appreciations and widening external deficits. Micro data show a strong association between credit booms and leverage ratios, firm values, and banking fragility. We also find that credit booms are larger in emerging economies, particularly in the nontradables sector; most emerging markets crises are associated with credit booms; and credit booms in emerging economies are often preceded by large capital inflows but not by financial reforms or productivity gains.

An Analysis of So-Called Export-led Growth
Description: The stylized fact that strong economic growth is usually accompanied with strong export growth leads many people to conclude that the export sector is the main driving force behind those episodes. The model in this paper, however, shows that the non-tradable sector may also generate high economic growth together with high export growth. Evidence shows that out of 71 "so-called" export-led growth episodes, only 37 of them are consistent with the "exports driving growth" hypothesis. Most of the remaining episodes (24 cases) experienced significant real exchange rate depreciation and are more likely to be characterized by "growth driving exports".

Are Weak Banks Leading Credit Booms? Evidence from Emerging Europe
Description: This paper examines the behavior of bank soundness indicators during episodes of brisk loan growth, using bank-level data for central and eastern Europe and controlling for the feedback effect of credit growth on bank soundness. No evidence is found that rapid loan expansion has weakened banks during the last decade, but over time weaker banks seem to have started to expand at least as fast as, and in some markets faster than, stronger banks. These findings suggest that during credit booms supervisors need to carefully monitor the soundness of rapidly expanding banks and stand ready to take action to limit the expansion of weak banks.

House Price Developments in Europe: A Comparison
Description: House prices in Europe have shown diverging trends, and this paper seeks to explain these differences by analyzing three groups of countries: the "fast lane", the average performers, and the slow movers. Price movements in the first two groups are found to be driven mostly by income and trends in user costs, and housing markets in these countries seem relatively more susceptible to adverse developments in fundamentals. Real house price declines among the slow movers are harder to explain, although ample supply, low home ownership, and less complete mortgage markets are likely factors. The impact of macroeconomic, prudential and structural policies on housing markets can be large and should be a factor in policy decisions.

Original Sin and Procylical Fiscal Policy: Two Sides of the Same Coin?
Description: The paper develops a simple model of sovereign debt where default both through direct repudiation and through inflation are possible and give rise to (endogenous) constraints on the currency composition and the level of public debt. This set up allows to show that procyclicality of fiscal policy in EMEs can arise as a by-product of the "original sin" and both can be explained by the presence of weak monetary institutions which cannot commit to price stability. The paper suggests that, as monetary institutions in EMEs strengthen, the "original sin" would fade away and the cyclical properties of fiscal policy would improve.

Investment Incentives and Effective Tax Rates in the Philippines: A Comparison With Neighboring Countries
Description: We compare the general tax provisions and investment incentives in the Philippines to six other east-Asian economies-Malaysia, Indonesia, Lao, Vietnam, Cambodia, and Thailand. We calculate effective tax rates and find that general effective tax rates are relatively high in the Philippines, while investment incentives are comparable to those in neighboring countries. Tax holidays are most attractive for very profitable firms, creating redundancy, and for investment in short-lived assets. We also consider recently-proposed tax reforms that would replace tax holidays by a reduced corporate income tax rate or a low tax on gross receipts. The results suggest that this would result in stronger incentives to invest, while government revenue increases. Alternatively, replacing holidays with a general reduction in the corporate tax rate and offering accelerated depreciation will either not provide the same incentives or be very costly.

Understanding the Inflationary Process in the GCC Region: The Case of Saudi Arabia and Kuwait
Description: This paper investigates the factors that affect inflation in the GCC region by examining the inflationary processes in Saudi Arabia and Kuwait. The paper utilizes a model that accounts for foreign factors affecting inflation, such as trading partners' inflation and exchange rate pass-through effect, as well as domestic influences. The analysis concludes that, in the long run, higher inflation in trading partners' countries is the main driving force for inflation in the two countries, with significant but lower contributions from the exchange rate pass-through effect and oil prices. Demand and money supply shocks affect inflation in the short run.
