Using a simple model of two-sided markets, we show that, in the social optimum, platform pricing leads to an inherent cost recovery problem. This result is driven by the positive externality of participation that users on either side of the market exert on the opposite side. The contribution of...

Using urban household surveys, we constructed a panel dataset to study the effects of the Argentine macroeconomic crisis of 1999-2002 with the aim of (1) identifying the most vulnerable households, (2) investigating whether employment in the public sector and government spending served to...

This paper uses a partial equilibrium framework to evaluate the relative efficiency, distributional and revenue implications of rice tariffs and targeted transfers in Madagascar, especially in the context of identifying their respective roles for poverty alleviation. Although there are likely to...

As in other sectors, competition in finance matters for allocative, productive and dynamic efficiency. Theory suggests, however, that unfettered competition is not first best given the special features of finance. I review these analytics and describe how to assess the degree of competition in...

Going forward, Korea faces two closely related challenges: sustaining economic growth against the backdrop of a rapidly aging population and ameliorating income inequality. This paper argues that a gradual increase in social spending could promote more sustainable and inclusive growth in Korea....

We estimate a unified measure of inclusive growth for emerging markets by integrating their economic growth performance and income distribution outcomes, using data over three decades. Country distributions are calibrated by combining PPP GDP per capita and income distribution from survey data....

In this paper, we explore how competition among stock exchanges, operated as self-regulatory organizations (SROs), affects the design of their members' surveillance. We develop a model where two for-profit SROs compete for trading volume, while brokers execute transactions on behalf of the...

This paper uses the Shapley Value decomposition technique to assess the factors behind the rise of inequality in China. It finds that, in many ways, inequality may have been an inevitable by-product of China’s investment and export-led growth model. Between Chinese households, we find that the...

Now close to 50 percent of GDP, this paper assesses the appropriateness of China’s current investment levels. It finds that China’s capital-to-output ratio is within the range of other emerging markets, but its economic growth rates stand out, partly due to a surge in investment...

The paper presents numerical simulations of various fiscal rules for oil-producing countries. Welfare implications are sensitive to the choice of the social welfare function, initial conditions, and non-oil growth prospects. The distribution of non-oil wealth is important for countries with...
