The Price of Capital Goods: A Driver of Investment Under Threat
Description: Over the past three decades, the price of machinery and equipment fell dramatically relative to other prices in advanced and emerging market and developing economies. Using cross-country and sectoral data, we show that the decline in the relative price of tangible tradable capital goods provided a significant impetus to the capital deepening that took place during the same time period. The broad-based decline in the relative price of machinery and equipment, in turn, was driven by the faster productivity growth in the capital goods producing sectors relative to the rest of the economy, and deeper trade integration, which induced domestic producers to lower prices and increase their efficiency. Our findings suggest an additional channel through which rising trade tensions and sluggish productivity could threaten real investment growth going forward.

The Measurement of External Accounts
Description: Growing international integration in trade and finance can challenge the measurement of external accounts. This paper presents a unified conceptual framework for identifying sources of mismeasurement of foreign investment income in current account balances. The framework allows to derive a precise definition of measurement distortions and an empirical strategy for estimating their importance. As an application, we empirically estimate two specific distortions related to inflation and retained earnings on portfolio equity for a broad set of countries. We find these may explain a non-trivial share of current account imbalances and that they are particularly relevant in countries with large external investment positions. We also discuss how merchanting and profit-shifting activities could lead to measurement distortions. We suggest areas for future research and underline the need to strengthen data collection efforts.

How Does Taxation Affect Hours Worked in EU New Member States?
Description: Hours worked vary widely across countries and over time. In this paper, we investigate the role played by taxation in explaining these differences for EU New Member States. By extending a standard growth model with novel data on consumption and labor taxes, we assess the evolution of trends in hours worked over the 1995-2017 period. We find that the inclusion of tax rates in the model significantly improves the tracking of hours. We also estimate the elasticity of hours (and its different margins) to quantify the deadweight loss introduced by consumption and labor taxes. We find that these taxes explain a large share of labor supply differences across EU New Member States and that the potential gains from policy actions are noteworthy.

Coping with Falling Oil Prices: The Different Fortunes of African Banks
Description: This paper studies the impact of declining oil prices on banks in sub-Saharan African oil-exporting countries. Results indicate that banks respond differently to an oil shock depending on their ownership: (i) domestic banks are the most adversely impacted and experience a deterioration in asset quality and liquidity; (ii) foreign-owned banks are the most resilient as they are able to improve asset quality and attract deposits but at the same time, they decelerate credit growth; in contrast, (iii) Pan-African Banks help stabilize overall credit but large banks in that segment experience reduced asset quality. These differentiated results suggest a tradeoff between maintaining credit growth and safeguarding financial stability in an oil slump which could be addressed by both micro- and macroprudential policies.

Domestic Amplifiers of External Shocks: Growth Accelerations and Reversals in Emerging Market and Developing Economies
Description: External conditions have been found to influence the tendency of emerging market and developing economies to experience episodes of growth accelerations and reversals. In this paper we study the role of domestic policies and other structural attributes in amplifying or mitigating the effect that shifts in external conditions have on growth patterns in emerging market and developing economies over the past five decades. We find that these economies can enhance the growth impulse from external conditions by strengthening their institutional frameworks and adopting a policy mix that protects trade integration; permits exchange rate flexibility; and ensures that vulnerabilities stemming from high current account deficits and external debt, as well as high public debt, are contained.

From Basel I to Basel III: Sequencing Implementation in Developing Economies
Description: Developing economies can strengthen their financial systems by implementing the main elements of global regulatory reform. But to build an effective prudential framework, they may need to adapt international standards taking into account the sophistication and size of their financial institutions, the relevance of different financial operations in their market, the granularity of information available and the capacity of their supervisors. Under a proportionate application of the Basel standards, smaller institutions with less complex business models would be subject to a simpler regulatory framework that enhances the resilience of the financial sector without generating disproportionate compliance costs. This paper provides guidance on how non-Basel Committee member countries could incorporate banks’ capital and liquidity standards into their framework. It builds on the experience gained by the authors in the course of their work in providing technical assistance on—and assessing compliance with—international standards in banking supervision.

Optimal Fiscal Spending and Reserve Accumulation Policies under Volatile Aid
Description: This paper assesses the optimal setting of fiscal spending and foreign exchange rate intervention policies in response to volatile foreign aid, in a small open economy model that incorporates typical features of low-income countries. Within a class of policy rules, it jointly considers the optimal aid spending and international reserve accumulation policies. The results show that it is optimal to adjust government spending gradually in response to unpredictable fluctuations in aid, while partially accumulating foreign exchange reserves to offset Dutch disease effects. Also, allocating relatively more of the government spending to productive public investment, and less to government consumption, is welfare improving.

Fiscal Consolidation and Public Wages
Description: A New Keynesian model with government production, public compensation, and unemployment is fit to U.S. data to study the macroeconomic and fiscal effects of public wage reductions. We find that accounting for the type of government spending is crucial for its macroeconomic implications. Although reductions in public wages and government purchases of goods have similar effects on total output and the fiscal balance, the former can raise private output slightly, in contrast to the substantial contractionary effects of the latter. In addition, the baseline estimation finds that exogenous public wage reductions decrease private wages. Model counterfactuals show that sufficiently rigid nominal private wages can reverse the response of private wages, as the rigidity dampens the labor reallocation effect from the public to private sector that exerts downward pressure on private wages.

The African Continental Free Trade Agreement: Welfare Gains Estimates from a General Equilibrium Model
Description: In March 2018, representatives of member countries of the African Union signed the African Continental Free Trade Area (AfCFTA) agreement. This agreement provides a framework for trade liberalization in goods and services and is expected to eventually cover all African countries. Using a multi-country, multi-sector general equilibrium model based on Costinot and Rodriguez-Clare (2014), we estimate the welfare effects of the AfCFTA for 45 countries in Africa. Three different model specifications—comprising both perfect competition and monopolistic competition—are used. Simulations include full elimination of import tariffs and partial but substantial reduction in non-tariff barriers (NTBs). Results reveal significant potential welfare gains from trade liberalization in Africa. As intra-regional import tariffs in the continent are already low, the bulk of these gains come from lowering NTBs. Overall gains for the continent are broadly similar under the three model specifications used, with considerable variation of potential welfare gains across countries in all model structures.

Market Regulation, Cycles and Growth in a Monetary Union
Description: We build a two-country currency union DSGE model with endogenous growth to assess the role of cross-country differences in product and labor market regulations for long-term growth and for the adjustment to shocks. We show that with endogenous growth, there is no reason to expect real income convergence. Large shocks, through endogenous TFP movements, can lead to permanent changes of output and real exchange rates. Differences are exacerbated when member countries have different product and labor market regulations. Less regulated economies are likely to have higher trend growth and recover faster from negative shocks. Results are consistent with higher inflation, lower employment and disappointing TFP growth rates experienced in the less reform-friendly euro area members.
