Finding the Bad Apples in the Barrel: Using the Market Value of Equity to Signal Banking Sector Vulnerabilities
Description: This paper measures the performance of different metrics in assessing banking system vulnerabilities. It finds that metrics based on equity market valuations of bank capital are better than regulatory capital ratios, and other metrics, in spotting banks that failed (bad apples). This paper proposes that these market-based ratios could be used as a surveillance tool to assess vulnerabilities in the banking sector. While the measures may provide a somewhat fuzzy signal, it is better to have a strategy for identifying bad apples, even if sometimes the apples turn out to be fine, than not being able to spot any bad apples before the barrel has been spoiled.

Crop Selection and International Differences in Aggregate Agricultural Productivity
Description: A large share of cross-country differences in productivity is explained by differences in agricultural productivity. Using a combination of sub-national agricultural statistics and geospatial datasets on crop-specific potential yields, we study the main drivers of this variation from a macroeconomic perspective. We find that differences in geographically-induced crop-specific comparative advantages can explain a substantial share of the variation in yields across the world. Data reveal substantial gaps between potential and observed yields in most countries. When decomposing these within country gaps, we find that crop selection gaps are on average larger than those induced by input usage alone. The results highlight the importance of understanding the interaction of geography and crop selection drivers in assessing aggregate agricultural productivity differences.

Weather Shocks and Output in Low-Income Countries: The Role of Policies and Adaptation
Description: We explore the extent to which macroeconomic policies, structural policies, and institutions can mitigate the negative relationship between temperature shocks and output in countries with warm climates. Empirical evidence and simulations of a dynamic general equilibrium model reveal that good policies can help countries cope with negative weather shocks to some extent. However, none of the adaptive policies we consider can fully eliminate the large aggregate output losses that countries with hot climates experience due to rising temperatures. Only curbing greenhouse gas emissions—which would mitigate further global warming—could limit the adverse macroeconomic consequences of weather shocks in a long-lasting way.

State Institutions and Tax Capacity: An Empirical Investigation of Causality
Description: Would better state institutions increase tax collection, or would higher tax collection help improve state institutions? In the absence of conclusive guidance from theory, this paper searches for an empirical answer to this question, using a panel dataset covering 110 non-resource-rich countries from 1996 to 2017. Employing a panel vector error correction model, the paper finds that tax capacity and state institutions cause and reinforce each other for a wide range of country groups. The bi-directional causality results suggest that developing tax capacity and building state institutions need to go hand in hand for best results, particularly in developing countries. Based on the impulse response analyses, the paper also finds that the causal effects in advanced economies are generally low in both directions, while in developing countries, both tax capacity and institutions shocks have larger positive impacts on institutions and tax capacity, respectively.

Liquidity Ratios as Monetary Policy Tools: Some Historical Lessons for Macroprudential Policy
Description: This paper explores what history can tell us about the interactions between macroprudential and monetary policy. Based on numerous historical documents, we show that liquidity ratios similar to the Liquidity Coverage Ratio (LCR) were commonly used as monetary policy tools by central banks between the 1930s and 1980s. We build a model that rationalizes the mechanisms described by contemporary central bankers, in which an increase in the liquidity ratio has contractionary effects, because it reduces the quantity of assets banks can pledge as collateral. This effect, akin to quantity rationing, is more pronounced when excess reserves are scarce.

The Impact of Remittances on Economic Activity: The Importance of Sectoral Linkages
Description: We propose a simple macroeconomic model with input-output sectoral linkages based on Acemoglu et al. (2016) to quantify how changes in aggregate demand due to additional income from household’s remittances propagates through the network of input-output linkages in Sub-Saharan African countries. We first propose two network centrality measures to assess the role of some sectors as key input providers in the economy. Then, we use these measures to quantify the effect of sectoral linkages on sectoral and total output following an increase in remittances inflows. Our empirical results suggest that the effects of remittances on recipient economies increase with the degree of linkages across sectors, which is especially prominent in the case of the financial intermediation sector. Our paper contributes to the emerging macroeconomic literature on the propagation of shocks across sectors and the implications for the whole economy.

Gender Equality and Electoral Violence in Africa: Unlocking the Peacemaking Potential of Women
Description: We examine the impact of gender equality on electoral violence in Africa using micro-level data from the sixth round of Afrobarometer surveys. The sample covers 30 countries. We find that gender equality is associated with lower electoral violence. Quantitatively, our estimates show that an increase in female-to-male labor force participation ratio by 1 percentage point is correlated with a reduction of the probability of electoral violence across the continent by around 4.2 percentage points. Our results are robust to alternative ways to measure electoral violence and gender equality, as well as to alternative specifications. The findings of this paper support the long-standing view that women empowerment contributes to the reduction of violence and underscore the urgency of addressing gender inequality in Africa.

Doing More for Less? New Evidence on Lobbying and Government Contracts
Description: Why do firms lobby? This paper exploits the unanticipated sequestration of federal budget accounts in March 2013 that reduced the availability of government funds disbursed through procurement contracts to shed light on this question. Following this event, firms with little or no prior exposure to the federal accounts that experienced cuts reduced their lobbying spending. In contrast, firms with a high degree of exposure to the cuts maintained and even increased their lobbying spending. This suggests that, when the same number of contractors competed for a piece of a reduced pie, the more affected firms likely intensified their lobbying efforts to distinguish themselves from the others and improve their chances of procuring a larger share of the smaller overall. These findings are stronger in government-dependent sectors and when there is intense competition. The evidence is more consistent with a rent-seeking explanation for lobbying.

Bank Lobbying: Regulatory Capture and Beyond
Description: In this paper, we discuss whether and how bank lobbying can lead to regulatory capture and have real consequences through an overview of the motivations behind bank lobbying and of recent empirical evidence on the subject. Overall, the findings are consistent with regulatory capture, which lessens the support for tighter rules and enforcement. This in turn allows riskier practices and worse economic outcomes. The evidence provides insights into how the rising political power of banks in the early 2000s propelled the financial system and the economy into crisis. While these findings should not be interpreted as a call for an outright ban of lobbying, they point in the direction of a need for rethinking the framework governing interactions between regulators and banks. Enhanced transparency of regulatory decisions as well as strenghtened checks and balances within the decision-making process would go in this direction.

Public Sector Balance Sheet Strength and the Macro Economy
Description: This paper introduces concepts of public sector balance sheet (PSBS) strength, taking into account different aspects of what governments own in addition to what they owe. It develops measures of PSBS strength and investigates their macroeconomic implications. Empirical estimations show that in their pricing of sovereign bonds, financial markets account for government assets and net worth in addition to their liabilities. Furthermore, economies with stronger public sector balance sheets experience shallower recessions and recover faster in the aftermath of economic downturns. This faster return to growth can be explained by the greater space for countercyclical fiscal policy in countries with stronger balance sheets.
