Marriage, Education, and Assortative Mating in Latin America

In this paper we establish six stylized facts related to marriage and work in Latin America and present a simple model to account for them. First, skilled women are less likely to be married than unskilled women. Second, skilled women are less likely to be married than skilled men. Third, married skilled men are more likely to work than unmarried skilled men, but married skilled women are less likely to work than unmarried skilled women. Fourth, Latin American women are much more likely to marry a less skilled husband compared to women in other regions of the world. Five, when a skilled Latin American woman marries down, she is more likely to work than if she marries a more or equally educated man. Six, when a woman marries down, she tends to marry the “better” men in that these are men that earn higher wages than those explained by the other observable characteristics. We present a simple game theoretic model that explains these facts with a single assumption: Latin American men, but not women, assign a greater value to having a stay-home wife.

The Building Blocks of Economic Complexity

For Adam Smith, wealth was related to the division of labor. As people and firms specialize in different activities, economic efficiency increases, suggesting that development is associated with an increase in the number of individual activities and with the complexity that emerges from the interactions between them. Here we develop a view of economic growth and development that gives a central role to the complexity of a country’s economy by interpreting trade data as a bipartite network in which countries are connected to the products they export, and show that it is possible to quantify the complexity of a country’s economy by characterizing the structure of this network. Furthermore, we show that the measures of complexity we derive are correlated with a country’s level of income, and that deviations from this relationship are predictive of future growth. This suggests that countries tend to converge to the level of income dictated by the complexity of their productive structures, indicating that development efforts should focus on generating the conditions that would allow complexity to emerge in order to generate sustained growth and prosperity.

Growth Diagnostic: Belize

Belize’s economic history shows marked periods of growth accelerations and recessions. There have been two such expansions and collapses in the past two decades, with disturbingly similar features. While not always initiated by public spending, these booms quickly became public-investment led, until ballooning budget, trade, and current account deficits and the resulting shrinking reserves and growing debt required home-grown adjustment programs. The huge cuts in public investment and sharp increases in reserve requirements created marked recessions. In addition, the second acceleration happened after a significant collapse in private savings, and ended up creating a huge debt overhang which has eliminated public savings. As a consequence, Belize is a country with a low savings, little access to international finance, and an extremely high domestic cost of finance. Access to finance is the binding constraint to economic growth.

We show that other potential constraints are not binding. Returns to education are low, and there is little to no infrastructure congestion, suggesting that although Belize is a structurally high-cost country, lacking complementary factors of production are not holding back growth. Furthermore, tax, inflation, exchange rate stability, and law and order do not seem to restrict investment through lowering appropriability. Finally, the country is not being held back by a lack of self-discovery. Although the movement to new export goods is critical for Belize’s growth, this process is being hindered by the cost and availability of finance, both public and private.

The appropriate policy stance is therefore to institutionalize fiscal discipline and gradually reduce the cost of credit. Given that low public savings are presently the result of expensive debt service, and also that foreign debt has created barriers to foreign borrowing and a heightened tax on financial intermediation which are key contributors to the high cost of finance, fiscal sustainability is key for drawing down the cost of finance in Belize. Reforms to prevent a lack of fiscal discipline in the future, particularly surrounding political cycles, are critical to end the past two decade’s ‘stop-and-go’ growth pattern. Finally, the government must address the rapidly rising implicit tax expenditure on investment promotion, as well as the fall in the tax take.

But these reductions in the domestic cost of finance will, as best, be gradual given the size of the debt. In the meantime, there is a need for public investment in areas such as public safety, road maintenance, and rural airports that if ignored, could have deleterious effects on long-term growth. Creative ways to finance such productivity-enhancing investments, which would not increase publicly-guaranteed debt, must be pursued.

In addition, the industrial strategy of the country must adapt to the current financial constraints and focus on attracting investors who aren’t subject to the high domestic interest rate, namely foreign investors. The current industrial strategy is not consistent with Belize’s constraints to growth.

Structural Transformation and Patterns of Comparative Advantage in the Product Space

In this paper we examine the product space and its consequences for the process of structural transformation. We argue that the assets and capabilities needed to produce one good are imperfect substitutes for those needed to produce other goods, but the degree of asset specificity varies widely. Given this, the speed of structural transformation will depend on the density of the product space near the area where each country has developed its comparative advantage. While this space is traditionally assumed to be smooth and continuous, we find that in fact it is very heterogeneous, with some areas being very dense and others quite sparse. We develop a measure of revealed proximity between products using comparative advantage in order to map this space, and then show that its heterogeneity is not without consequence. The speed at which countries can transform their productive structure and upgrade their exports depends on having a path to nearby goods that are increasingly of higher value.

South Africa’s Export Predicament

This paper explores export performance in South Africa over the past 50 years, and concludes that a lagging process of structural transformation is part of the explanation for stagnant exports per capita. Slow structural transformation in South Africa is found to be a consequence of the peripheral nature of South Africa’s productive capabilities. We apply new tools to evaluate South Africa’s future prospects for structural transformation, as well as to explore the sectoral priorities of the DTI’s draft industrial strategy. We then discuss policy conclusions, advocating an ‘open-architecture’ industrial policy where the methods applied herein are but one tool to screen private sector requests for sector-specific coordination and public goods.

China and the Global Economy: Medium-term Issues and Options – A Synthesis Report

China’s economic and social achievements since the beginning of reform and opening are unprecedented in global history. Managing the growth process in this continuously changing environment has required great skill and the use of unconventional economic policy. Now China has entered a new era in its development process with a set of challenges largely different from those of the recent past. Some problems – such as growing internal and external structural imbalances, increasing income and regional inequality – have arisen from, or been exacerbated by, the very pattern and success of high growth since reforms began. Others are newly posed by rapid changes in the global economy. These challenges can best be tackled in an integrated and coordinated fashion. This report, supported by the China Economic Research and Advisory Programme (CERAP), identifies the primary challenges facing China today and presents options for meeting them.

Growth Diagnostics

Most well-trained economists would agree that the standard policy reforms included in the Washington Consensus have the potential to be growth-promoting.

What the experience of the last 15 years has shown, however, is that the impact of these reforms is heavily dependent on circumstances. Policies that work wonders in some places may have weak, unintended, or negative effects in others.

We argue in this paper that this calls for an approach to reform that is much more contingent on the economic environment, but one that also avoids an anything goes attitude of nihilism. We show it is possible to develop a unified framework for analyzing and formulating growth strategies that is both operational and based on solid economic reasoning. The key step is to develop a better understanding of how the binding constraints on economic activity differ from setting to setting. This understanding can then be used to derive policy priorities, in a way that uses efficiently the scarce political capital of reformers.

Our approach is motivated by three considerations. First, while development is a broad concept entailing the raising of human capabilities in general,we believe increasing economic growth rates is the central challenge that developing nations face. Higher levels of living standards are the most direct route to achieving improvements in social and human indicators. Reform strategies should be principally targeted at raising rates of growth that is, they should be growth strategies.

Second, trying to come up with an identical growth strategy for all countries, regardless of their circumstances, is unlikely to prove productive. Growth strategies are likely to differ according to domestic opportunities and constraints.

There are of course some general, abstract principles such as property rights, the rule of law, market-oriented incentives, sound money, and sustainable public finances which are desirable everywhere. But turning these general principles into operational policies requires considerable knowledge of local specific cities.

Third, it is seldom helpful to provide governments with a long list of reforms, many of which may not be targeted at the most binding constraints on economic growth. Governments face administrative and political limitations, and their policy-making capital is better deployed in alleviating binding constraints than in going after too many targets all at once. So growth strategies require a sense of priorities. What we propose to do in this paper is to develop a framework for growth diagnostics that is, a strategy for figuring out the policy priorities. The strategy is aimed at identifying the most binding constraints on economic activity, and hence the set of policies that, once targeted on these constraints at any point in time, is likely to provide the biggest bang for the reform buck.

The methodology that we propose for this can be conceptualized as a decision tree (see Figure 1, discussed below). We start by asking what keeps growth low. Is it inadequate returns to investment, inadequate private appropriability of the returns, or inadequate access to finance? If it is a case of low returns, is that due to insufficient investment in complementary factors of production (such as human capital or infrastructure)? Or is it due to poor access to imported technologies? If it is a case of poor appropriability, is it due to high taxation, poor property rights and contract enforcement, labor-capital conflicts, or learning and coordination externalities? If it is a case of poor finance, are the problems with domestic financial markets or external ones? And so on.

Then we discuss the kind of evidence that would help answer these question one way or another. We also illustrate the practical implications of this approach by drawing on examples from specific countries.

Aside from providing a useful manual for policymakers, our approach has the advantage that it is broad enough to embed all existing development strategies as special cases. It can therefore unify the literature and help settle prevailing controversies. For example, our framework will clarify that doctrinal differences on development policy between proponents of the Washington Consensus and of state-led strategies, or between pro-globalizers and cautious globalizers are grounded in divergent evaluations about the nature of the binding constraints on growth. Making these differences explicit, and clarifying the nature of the evidence that can resolve them, can move us forward to a more productive policy agenda.

The outline of the paper is as follows. We first lay out the conceptual framework, linking our terminology of binding constraints to standard economic models. In particular, we relate our framework to theories of second-best and partial reform and of endogenous growth. We next cast the framework in the form of a decision tree, and discuss the nature of the evidence that is required to move along the nodes of the tree. In the final section we carry out an analysis of several “archetypal” cases, each representing a different syndrome or combination of binding constraints.

The Challenge of Fiscal Adjustment in a Democracy: The Case of India

India’s fiscal problem has deep roots in its federal fiscal system, where multiple players find it difficult to coordinate adjustment. The size and closed nature of the Indian economy, aided by its deep domestic capital market and large captive pool of domestic savings, has disguised the cost of fiscal laxity and complicated the building of a consensus on reform. The new fiscal responsibility act establishes a new rules-based system to overcome this coordination failure. To strengthen the framework, we recommend an autonomous scorekeeper and the extension of similar rules to the state governments as part of a comprehensive reform of the federal system.

Economic Development as Self-Discovery

In the presence of uncertainty about what a country can be good at producing, there can be great social value to discovering costs of domestic activities because such discoveries can be easily imitated. We develop a general-equilibrium framework for a small open economy to clarify the analytical and normative issues. We highlight two failures of the laissez-faire outcome: there is too little investment and entrepreneurship ex ante, and too much production diversification ex post. Optimal policy consists of counteracting these distortions: to encourage investments in the modern sector ex ante, but to rationalize production ex post. We provide some informal evidence on the building blocks of our model.
