The Consequences of Policy Uncertainty: Disconnects and Dilutions in the South African Real Effective Exchange Rate-Export Relationship
Description: In recent years, the link between the real effective exchange rate (REER) and exports in South Africa has weakened. While exports still rise in response to REER depreciations, the REER-export elasticity is below historical estimates. The literature has put forward a number of possible explanations, from multi-national supply-chains to muted exchange rate pass-through. This research explores the role of policy uncertainty in reducing the responsiveness of exports to relative price changes. We construct a novel “news chatter” measure of policy uncertainty and examine how it, paired with other supply-side constraints, can improve our understanding of export performance. We find that increased policy uncertainty diminishes the responsiveness of exports to the REER and has short and long-run level effects on export performance. Finally, we show that a measure of competitiveness that adjusts for uncertainty and supply-side constraints greatly outperforms the REER in tracking exports performance.

What Does Aid Do to Fiscal Policy? New Evidence
Description: Foreign aid is a sizable source of government financing for several developing countries and its allocation matters for the conduct of fiscal policy. This paper revisits fiscal effects of shifts in aid dependency in 59 developing countries from 1960 to 2010. It identifies structural shifts in aid dependency: upward shifts (structural increases in aid inflows) and downward shifts (structural decreases in aid inflows). These shifts are treated as shocks in aid dependency and treatment effect methods are used to assess the fiscal effects of aid. It finds that shifts in aid dependency are frequent and have significant fiscal effects. In addition to traditional evidence of tax displacement and “aid illusion,” we show that upward shifts and downward shifts in aid dependency have asymmetric effects on the fiscal accounts. Large aid inflows undermine tax capacity and public investment while large reductions in aid inflows tend to keep recipients’ tax and expenditure ratios unchanged. Moreover, the tax displacement effects tend to be temporary while the impact on expenditure items are persistent. Finally, we find that the undesirable fiscal effects of aid are more pronounced in countries with low governance scores and low absorptive capacity, as well as those with IMF-supported programs.

Inequality, Gender Gaps and Economic Growth: Comparative Evidence for Sub-Saharan Africa
Description: A growing body of empirical evidence suggests that inequality—income or gender related—can impede economic growth. Using dynamic panel regressions and new time series data, this paper finds that both income and gender inequalities, including from legal gender-based restrictions, are jointly negatively associated with per capita GDP growth. Examining the relationship for countries at different stages of development, we find that this effect prevails mainly in lower income countries. In particular, per capita income growth in sub-Saharan Africa could be higher by as much as 0.9 percentage points on average if inequality was reduced to the levels observed in the fastgrowing emerging Asian countries. High levels of income inequality in sub-Saharan Africa appear partly driven by structural features. However, the paper’s findings show that policies that influence the opportunities of low-income households and women to participate in economic activities also matter and, therefore, if well-designed and targeted, could play a role in alleviating inequalities.

Changes in Prudential Policy Instruments — A New Cross-Country Database
Description: This paper documents the features of a new database that focuses on changes in the intensity in the usage of several widely used prudential tools, taking into account both macro-prudential and micro-prudential objectives. The database coverage is broad, spanning 64 countries, and with quarterly data for the period 2000Q1 through 2014Q4. The five types of prudential instruments in the database are: capital buffers, interbank exposure limits, concentration limits, loan to value (LTV) ratio limits, and reserve requirements. A total of nine prudential tools are constructed since some useful further decompositions are presented, with capital buffers divided into four subindices: general capital requirements, real state credit specific capital buffers, consumer credit specific capital buffers, and other specific capital buffers; and with reserve requirements divided into two sub-indices: domestic currency capital requirements and foreign currency capital requirements. While general capital requirements have the most changes from the cross-country perspective, LTV ratio limits and reserve requirements have the largest number of tightening and loosening episodes. We also analyze the instruments’ usage in relation to the evolution of key variables such as credit, policy rates, and house prices, finding substantial differences in the patterns of loosening or tightening of instruments in relation to business and financial cycles.

Foreign Bank Subsidiaries’ Default Risk during the Global Crisis: What Factors Help Insulate Affiliates from their Parents?
Description: This paper examines the association between the default risk of foreign bank subsidiaries in developing countries and their parents during the global financial crisis, with the purpose of determining the size and sign of this correlation and, more importantly, understanding what factors can help insulate affiliates from their parents. We find evidence of a significant and robust positive correlation between parent banks’ and foreign subsidiaries’ default risk. This correlation is lower for subsidiaries that have a higher share of retail deposit funding and that are more independently managed from their parents. Host country bank regulations also influence the extent to which shocks to the parents affect the subsidiaries’ default risk. In particular, the correlation between the default risk of subsidiaries and their parents is lower for subsidiaries operating in countries that impose higher capital, reserve, provisioning, and disclosure requirements, and tougher restrictions on bank activities.

Global Financial Conditions and Monetary Policy Autonomy
Description: Is the Mundell-Fleming trilemma alive and well? International co-movement of asset prices takes place alongside synchronized business cycles, complicating the identification of financial spillovers and assessments of monetary policy autonomy. A benchmark for interest rate comovement is to impose the null hypothesis that central banks respond only to the outlook for domestic inflation and output. We show that common approaches used to estimate interest rate spillovers tend to understate the degree of monetary autonomy enjoyed by small open economies with flexible exchange rates. We propose an empirical strategy that partials out those spillovers that are associated with impaired monetary autonomy. Using this approach, we revisit the predictions of the trilemma and find more compelling evidence that flexible exchange rates deliver monetary autonomy than prior work has suggested.

External Adjustment in Oil Exporters: The Role of Fiscal Policy and the Exchange Rate
Description: After the decline in oil prices, many oil exporters face the need to improve their external balances. Special characteristics of oil exporters make the exchange rate an ineffective instrument for this purpose and give fiscal policy a sizeable role. These conclusions are supported by regression analysis of the determinants of the current account balance and of the trade balance. The results show little or no relationship with the exchange rate and, especially for the less diversified oil exporters (including the Gulf Cooperation Council), a strong relationship with the fiscal balance or government spending.

Chinese Imports: What’s Behind the Slowdown?
Description: Real imports in China have decelerated significantly over the last two years to below 4 percent (yoy) from double-digit growth in previous years. Weaker investment, partly due to progress in rebalancing from investment to consumption, has been the main factor accounting for about 40–50 percent of slowdown during this period. Weaker exports also account for about 40 percent of slowdown, of which about a quarter is due to stronger RMB. Onshoring—substitution of imported intermediate inputs with domestic production—has not been an additional drag over this period but it continues to slow import growth at a similar pace as previous periods. There is large uncertainty about the impact of rebalancing on the import slowdown due to difficulties in identifying the counterfactual nonrebalancing path.

China and Asia in Global Trade Slowdown
Description: Asia and China made disproportionate contributions to the slowdown of global trade growth in 2015. China’s import growth slowed starkly, driven by both external and domestic factors, including a rebalancing of demand. Econometric results point to weak investment and rebalancing as the main causes of the import slowdown. Spillover effects from China’s rebalancing are estimated for some 60 countries using value-added trade data, and are found to be more negative on Asia and commodity exporters than others.

Estimating the Effects of the Trans-Pacific Partnership (TPP) on Latin America and the Caribbean (LAC)
Description: In February 2016, twelve Pacific Rim countries signed the agreement on the Trans Pacific Partnership (TPP), one of the largest and most comprehensive trade deals in history. While there are several estimates of the likely effects of the TPP, there is no systematic study on the effects on all Latin American countries. We present the results from applying a multi-sector model with perfect competition presented by Costinot and Rodriguez-Clare (2014). The exercise, based on input-output data for 189 countries and 26 sectors, shows that (i) Asian TPP members are estimated to benefit most from the agreement, (ii) negative spillovers to non-TPP LAC countries appear to be of a different order of magnitude than the gains of members, and (iii) some non-TPP LAC countries may experience relatively large benefits from joining the TPP. As a cautionary note, however, we point out that even a cursory cross-study comparison shows that there is considerable uncertainty regarding the potential effects of the TPP for both members and non-members.
