Growth Slowdowns and the Middle-Income Trap

The “middle-income trap” is the phenomenon of hitherto rapidly growing economies stagnating at middle-income levels and failing to graduate into the ranks of high-income countries. In this study we examine the middle-income trap as a special case of growth slowdowns, which are identified as large sudden and sustained deviations from the growth path predicted by a basic conditional convergence framework. We then examine their determinants by means of probit regressions, looking into the role of institutions, demography, infrastructure, the macroeconomic environment, output structure and trade structure. Two variants of Bayesian Model Averaging are used as robustness checks. The results—including some that indeed speak to the special status of middle-income countries—are then used to derive policy implications, with a particular focus on Asian economies.

The Macroeconomics of Scaling Up Aid; Lessons from Recent Experience

This study analyzes key issues associated with large increases in aid, including absorptive capacity, Dutch disease, and inflation. The authors develop a framework that emphasizes the different roles of monetary and fiscal policy and apply it to the recent experience of five countries: Ethiopia, Ghana, Mozambique, Tanzania, and Uganda. These countries have often found it difficult to coordinate monetary and fiscal policy in the face of conflicting objectives, notably to spend the aid money on domestic goods and to avoid excessive exchange rate appreciation.

How did the crisis in international funding markets affect bank lending? Balance sheet evidence from the United Kingdom

Evidence abounds on the propagation of financial stresses originating in the US mortgage market to banking systems worldwide through international funding markets. But the transmission of this external funding shock to the real economy via bank lending is surprisingly underexamined, given the central importance ascribed to this channel of contagion by policymakers. This paper provides evidence of this transmission for the UK-resident banking system, the largest in the world by asset size. It uses a novel data set, created from detailed and confidential balance sheet data reported by individual banks quarterly to the Bank of England. I find that the shock to foreign funding caused a substantial pullback in domestic lending. The results are derived using a range of instruments to correct for endogeneity and omitted variable bias. Foreign subsidiaries and branches reduced lending by a larger amount than domestically owned banks, while the latter calibrated the reduction in domestic lending more closely to the size of the funding shock.

The Demographic Dividend: Evidence from the Indian States

Large cohorts of young adults are poised to add to the working-age population of developing economies. Despite much interest in the consequent growth dividend, the size and circumstances of the potential gains remain under-explored. This study makes progress by focusing on India, which will be the largest individual contributor to the global demographic transition ahead. It exploits the variation in the age structure of the population across Indian states to identify the demographic dividend. The main finding is that there is a large and significant growth impact of both the level and growth rate of the working age ratio. This result is robust to a variety of empirical strategies, including a correction for inter-state migration. The results imply that a substantial fraction of the growth acceleration that India has experienced since the 1980s - sometimes ascribed exclusively to economic reforms - is attributable to changes in the country’s age structure. Moreover, the demographic dividend could add about 2 percentage points per annum to India’s per capita GDP growth over the next two decades. With the future expansion of the working age ratio concentrated in some of India’s poorest states, income convergence may well speed up, a theme likely to recur on the global stage.

A Contribution to the Empirics of Total Factor Productivity

Our paper analyzes the causal links between human capital accumulation and growth in total factor productivity (TFP). In particular, it tests the NelsonPhelps hypothesis that human capital is crucial in enabling the imitation of technologies developed at the frontier. To this end we calculate TFP for a sample of 86 heterogeneous countries over the period 1960-1990 and investigate whether there has been (conditional) convergence in TFP. Our regressions use a variety of GMM estimators in a dynamic panel framework with fixed eects. Human capital is found to have a positive and significant eect on the long run growth path of TFP. Countries are found to be converging to these growth paths at a rate of about 3% a year. This work goes some way in resolving the debate over whether factor accumulation or TFP increases are more important for economic growth; while TFP dierences explain most of the static variation in GDP across countries, human capital accumulation is a crucial determinant of the dynamic path of TFP

The Refugee Surge in Europe : Economic Challenges

Against the background of political turmoil in the Middle-East, Europe faces an unprecedented surge in asylum applications. In analyzing the economic impact of this inflow, this paper draws from the experience of previous economic migrants and refugees, mindful of the fact that the characteristics of economic migrants can be different from refugees. In the short-run, additional public expenditure will provide a small positive impact on GDP, concentrated in the main destination countries of Germany, Sweden and Austria. Over the longer-term, depending on the speed and success of the integration of refugees in the labor market, the increase in the labor force can have a more lasting impact on growth and the public finances. Here good policies will make an important difference. These include lowering barriers to labor markets for refugees, for example through wage subsidies to employers, and, in particular, reducing legal barriers to labor market participation during asylum process, removing obstacles to entrepreneurship/self-employment, providing job training and job search assistance, as well as language skills. While native workers often have legitimate concerns about the impact of immigrants on wages and employment, past experience indicates that any adverse effects are limited and temporary.

Identifying channels of credit substitution when bank capital requirements are varied

What kinds of credit substitution, if any, occur when changes to banks’ minimum capital requirements induce banks to change their supply of credit? The question is central to the new ‘macroprudential’ policy regimes that have been constructed in the wake of the global financial crisis, under which minimum capital ratio requirements for banks will be employed to control the supply of bank credit. Regulatory efforts to influence the aggregate supply of credit may be thwarted to some degree by ‘leakages’, as other credit suppliers substitute for the variation induced in the supply of credit by regulated banks. Credit substitution could occur through foreign banks operating domestic branches that are not subject to capital regulation by the domestic supervisor, or through bond and stock markets. The UK experience for the period 1998-2007 is ideally suited to address these questions, given its unique regulatory history (UK bank regulators imposed bank-specific and time-varying capital requirements on regulated banks), the substantial presence of both domestically regulated and foreign regulated banks, and the United Kingdom’s deep capital markets. We show that leakage by foreign branches can occur either as a result of competition between branches and regulated banks that are parts of separate banking groups, or because a foreign banking group shifts loans from its UK-regulated subsidiary to its affiliated branch. The responsiveness of affiliated branches is nearly twice as strong. We do not find any evidence for leakages through capital markets. These findings reinforce the need for the type of international co-ordination, specifically reciprocity in capital requirement regulation, which is embedded in Basel III and the European CRD IV directive, which will be gradually phased in starting January 2014.

How Did the Crisis in International Funding Markets Affect Bank Lending? Balance Sheet Evidence from the UK

Evidence abounds on the propagation of financial stresses originating in the US mortgage market to banking systems worldwide through international funding markets. But the transmission of this external funding shock to the real economy via bank lending is surprisingly under-examined, given the central importance ascribed to this channel of contagion by policymakers. This paper provides evidence of this transmission for the UK-resident banking system, the largest in the world by asset size. It uses a novel dataset, created from detailed balance sheet data reported by resident banks quarterly to the Bank of England. It finds that the shock to foreign funding during the financial crisis caused a substantial pullback in domestic lending. A range of instrumental variables are used to correct for endogeneity and omitted variable bias, and the results are robust to various sensitivity tests. Resident subsidiaries and branches of foreign-owned banks reduced lending by a larger amount than domestically-owned banks, while the latter calibrated the reduction in domestic lending more closely to the size of the funding shock.

Where Did All the Aid Go? An Empirical Analysis of Absorption and Spending

This paper examines the macroeconomic usage of aid using panel data for a broad sample of aid-recipients. By definition an increase in aid must go toward a reduction in the current account balance (absorbed aid), an increase in capital outflows, or reserve accumulation. It is found that short-run absorption is typically very low, with much aid exiting through the capital account. Moreover, aid spending, defined in terms of the increase in government fiscal expenditures as a result of aid, is significantly greater than aid absorption, implying that aid systematically leads to an injection of domestic liquidity in recipient economies. The evidence here may help illuminate the rather weak link between aid and growth found in the literature. It reinforces the case for greater coordination between fiscal and monetary authorities in response to aid inflows.

The Domestic Credit Supply Response to International Bank Deleveraging: Is Asia Different?

During the global financial crisis, European banks contracted foreign claims on recipient economies sharply. This paper examines the impact of that deleveraging on credit supply in recipient economies, with a particular focus on Asia. Identification is achieved by exploiting heterogeneity in ex-ante patterns of funding reliance on different European banking systems, and in variation in the ratio of local claims in local currency to total foreign claims in recipient economies. These sources of variation are used to create instruments for the deleveraging shock. We find that the contraction in European bank foreign claims was associated with a substantial reduction in domestic credit supply in a broad sample of countries. However, the credit supply response in Asia was only about half the size of the response in non-Asian countries, possibly due to a more robust policy response and healthier local bank balance sheets at the outset of the crisis.
