In Poor Economics, Abhijit Banerjee and Esther Duflo eschew grand theorizing about poverty reduction in favor of an approach in which intelligently designed and tested small interventions, based on a scientific understanding of the lives of the poor, marginally improve their welfare. In so doing, they describe the findings from the recent large literature describing the behavior and institutions of the poor and the consequences of policy and experimental interventions targeted to poverty populations. In this review, I assess whether “thinking small” with its associated policy regime of transfers, subsidies, and nudges, is both a practical and effective policy prescription for “fighting” poverty and whether the set of studies that have focused on populations that have not escaped poverty has improved our fundamental understanding of both the consequences and causes of poverty.

Previous studies of the U.S. Great Depression find that increased government spending and taxation contributed little to either the dramatic downturn or the slow recovery. These studies include only one type of capital taxation: a business profits tax. The contribution is much greater when the analysis includes other types of capital taxes. A general equilibrium model extended to include taxes on dividends, property, capital stock, excess profits, and undistributed profits predicts patterns of output, investment, and hours worked that are more like those in the 1930s than found in earlier studies. The greatest effects come from the increased taxes on corporate dividends and undistributed profits.

In this paper, we decompose city size wage premia into various components. We base these decompositions on an estimated on-the-job search model that incorporates latent ability, search frictions, firm-worker match quality, human capital accumulation and endogenous migration between large, medium and small cities. Counterfactual simulations of the model indicate that variation in returns to experience and differences in wage intercepts across location type are the most important mechanisms contributing to observed city size wage premia. Variation in returns to experience is more important for generating wage premia between large and small locations while differences in wage intercepts are more important for generating wage premia betwen medium and small locations. Sorting on unobserved ability within education group and differences in labor market search frictions and distributions of firm-worker match quality contribute little to observed city size wage premia. These conclusions hold for separate samples of high school and college graduates.

[We compare the dividend policies of publicly and privately held firms in order to help identify the forces shaping corporate dividends, and shed light on the behavior of privately held companies. We show that private firms smooth dividends significantly less than their public counterparts, suggesting that the scrutiny of public capital markets plays a central role in the propensity of firms to smooth dividends over time. Public firms pay relatively higher dividends that tend to be more sensitive to changes in investment opportunities than otherwise similar private firms. Ultimately, ownership structure and incentives play key roles in shaping dividend policies.]

Why is it difficult to restructure sovereign debt in a timely manner? In this paper, we present a theory of the sovereign debt-restructuring process in which delay arises as individual creditors hold up a settlement in order to extract greater payments from the sovereign. We then use the theory to analyse recent policy proposals aimed at ensuring equal repayment of creditor claims. Strikingly, we show that such collective action policies may increase delay by encouraging free riding on negotiation costs, even while preventing hold-up and reducing total negotiation costs. A calibrated version of the model can account for observed delays and finds that free riding is quantitatively relevant: whereas in simple low-cost debt-restructuring operations, collective mechanisms will reduce delay by more than 60%, in high-cost complicated restructurings, the adoption of such mechanisms results in a doubling of delay.

This paper shows that a New Year's gambling preference of individual investors impacts prices and returns of assets with lottery features. January call options, especially the out-of-the-money calls, have higher retail demand and are the most expensive and actively traded. Lottery-type stocks outperform their counterparts in January but tend to underperform in other months. Retail sentiment is more bullish in lottery-type stocks in January than in other months. Furthermore, lottery-type Chinese stocks outperform in the Chinese New Year's Month but not in January. This New Year effect provides new insights into the broad phenomena related to the January effect.

I analyze optimal loan modification schemes in a stochastic home price and stochastic interest-rate environment. Lenders maximize loan values by managing the borrower’s option to default on the loan and prepayment option. Given negative equity, controlling for the borrower’s ability to pay, rate reductions and maturity extensions result in a higher probability of redefault by homeowners even after modification of their loans. In contrast, loan write-downs (the Principal Principle), not a favored recipe, are value maximizing for the lender. A shared-appreciation mortgage enhances the ability to pay, mitigates adverse selection, and reduces the present value of expected deadweight foreclosure costs.

This paper comprehensively reviews the Accounting for Income Taxes (AFIT) literature. We begin by identifying four distinctive aspects of AFIT and briefly covering the rules surrounding AFIT. We then review the existing studies in detail and offer suggestions for future research. We emphasize the research questions that have been addressed (most of which relate to whether the tax accounts are used to manage earnings and whether the tax accounts are priced by equity market participants). We also highlight areas that have not received much research attention and that warrant future analysis.

In the four regions (North America, Europe, Japan, and Asia Pacific) we examine, there are value premiums in average stock returns that, except for Japan, decrease with size. Except for Japan, there is return momentum everywhere, and spreads in average momentum returns also decrease from smaller to bigger stocks. We test whether empirical asset pricing models capture the value and momentum patterns in international average returns and whether asset pricing seems to be integrated across the four regions. Integrated pricing across regions does not get strong support in our tests. For three regions (North America, Europe, and Japan), local models that use local explanatory returns provide passable descriptions of local average returns for portfolios formed on size and value versus growth. Even local models are less successful in tests on portfolios formed on size and momentum.
