Saving China's stock market

What were the economic benefits and costs of preventing a stock market meltdown during the summer of 2015 by the Chinese government intervention? We answer this question by estimating the value creation for the stocks purchased by the government between the period starting with the market crash in mid-June and the market recovery in September. We find that the government intervention...

The IMF’s role in Greece in the context of the 2010 stand-by arrangement

In April 2010, Greece became the first euro area country to request financial support from the IMF. The IMF joined the European Commission (EC) and the European Central Bank (ECB)—thus constituting what informally came to be known as the troika—in providing emergency financing, with the Fund’s contribution taking the form of a €30 billion three-year Stand-By Arrangement (SBA)...

Does ethnic diversity decrease economic interactions? Evidence from exchange networks in rural Gambia

Using a unique dataset collected in 59 rural Gambian villages, we study how ethnic heterogeneity is related to the structure of four economic exchange networks: land, labor, inputs and credit. We find that different measures of village-level ethnic fragmentation are mostly uncorrelated with network structure. At a more disaggregated level, household heads belonging to ethnic...

Dynamic mean preserving spreads

We extend the celebrated Rothschild and Stiglitz (1970) definition of Mean Preserving Spreads to scalar diffusion processes. We provide sufficient conditions under which a family of diffusion processes satisfies the dynamic counterparts to the famous Rothschild and Stiglitz integral conditions. We prove that the only Brownian bridge with non-constant drift that displays the Dynamic...

Coping with migration-induced urban growth: addressing the blind spot of UN habitat

The demography of cities in the 21st century will be shaped, to a large extent, by migration. This paper argues that the rights-based approach to urban policy advocated in the preparatory work of Habitat III, the UN Conference on Housing and Sustainable Urban Development to be held in October 2016 in Quito, Ecuador, may not be conducive to this goal. The approach lacks a contextual...

Testing for the best instrument to generate sustainable food consumption

The increase in the level of greenhouse gas (GHG) emissions in the atmosphere in the last centuries, and the subsequent increase in temperature, has been a widely studied area in the last few decades. Climate change has become a key item on the political agenda due to concerns regarding the sustainability of current human consumption for future generations. Consumption of food and...

Economic growth and agricultural land conversion under uncertain productivity improvements in agriculture

We study how stochasticity in the evolution of agricultural productivity interacts with economic and population growth, and the associated demand for food. We use a two-sector Schumpeterian model of growth, in which a manufacturing sector produces the traditional consumption good and an agricultural sector produces food to sustain contemporary population. In addition, sectors differ...

When corporatism leads to corporate governance failure : the case of Swiss watch industry

Corporatism is often seen as the way Swiss stakeholders in business and politics handle industrial challenges in a reasonable and flexible way. The following publication argues, however, that the emergence of corporatist structures in the Swiss watch industry has often encouraged rent-seeking and collusion at the expense of the creation of new markets through innovation. This legacy...

Do foreign demand shocks impact company sales in France?

An interaction can be observed between a company’s level of exports and its domestic sales. Estimates made using data on French companies show that a 10% increase (decrease) in exports is accompanied, in the same year, by a 1% to 3% increase (decrease) in domestic sales. This strong interaction between sales in different markets can result from short-term funding constraints that...

Global population growth, technology and Malthusian constraints: a quantitative growth theoretic perspective

We structurally estimate a two-sector Schumpeterian growth model with endogenous population and finite land reserves to study the long-run evolution of global population, technological progress and the demand for food. The estimated model closely replicates trajectories for world population, GDP, sectoral productivity growth and crop land area from 1960 to 2010. Projections from 2010...

Saving by default: evidence from a field experiment in Rural India

Worldwide, people are gaining access to a formal bank account, which allows account-based instead of cash payments. Based on a novel randomized control trial, we document that the payment method is an important determinant of savings behavior. In rural India, we study the effect on savings of allocating identical weekly payments on a bank account (treated) or in cash (control). The...

Better more than one: portfolio currency pricing and exchange rate hedging

This paper examines the relationship between the composition of exporters' currency pricing portfolio - number and value of product sales in different currencies at a destination - and their success in trade as measured by continuing to their exporting activity. Detailed investigation of currency choice data of Russian exporters between 2005-2009 shows that many exporters use...

Why give aid to resource-rich autocrats?

Why give aid to resource-rich autocrats? We find that the interaction between natural resources and most forms of international aid results in enhanced political instability in most autocratic countries. Interestingly, some types of government aid (notably humanitarian aid) do not have this effect, indicating that the impact of aid varies with its form. Furthermore, we find that only...

Latent factor models for large and mixed-frequency data in finance and macroeconomics

My thesis considers new latent factor models, and their estimation methodologies, suitable for settings relatively unexplored in the econometric literature as (i) a nonlinear model for the joint dynamics of a large cross-sectional distribution of asset returns, and the persistence of the ranks of the individuals inside it; (ii) approximate linear latent factor models for large...

The quest to lower high remittance costs to Africa: a brief review of the use of mobile banking and bitcoins

The paper reviews the latest technological tools that arguably can contribute to reducing the excessively high costs of remittance transactions in Africa. Indeed, despite huge remittance inflows to and within the continent, Africa is the most expensive destination to send money to. As remittances have become more important than Overseas Development Assistance and Foreign Direct...

Fire-sale FDI or business as usual?

Motivated by a set of stylized facts, we develop a model of cross-border mergers and acquisitions (M&As;) to study foreign direct investment (FDI) in emerging markets. We compare acquisitions undertaken during financial crises – so called fire-sale FDI –with acquisitions made during non-crisis periods to examine whether the outcomes differ in the ways predicted by the model....

Options for trade, finance and development: getting the institutions right

The basic tenet of the present policy paper is that economic institutions are the key determinant of economic growth and development, and that policy-makers and developing country governments dealing with trade and finance must concentrate on “getting the institutions right.” In order to be implementable, policy recommendations must correct inefficiencies that the market system will...
