Knowledge that Transforms

We extend Jin and Myers’s (2006) model to derive the relation between stock price crash risk and operating leverage (i.e., the fraction of fixed costs in total costs). The model predicts that (1) firms’ operating leverage decreases as stock price crash risk increases and (2) the negative effect of crash risk on operating leverage is more pronounced when firms are closer to the crash threshold or when managers face higher costs of stock price crashes. We empirically test the model predictions using a large sample of manufacturing firms in the US and find consistent results. Further analysis shows that higher levels of crash risk lead to a less sticky cost behavior. In addition, crash risk–driven operating deleveraging effectively reduces stock return volatility and enhances operating performance in subsequent years. Collectively, our findings reveal that crash-prone firms adopt a more flexible cost structure to delay stock price crashes and mitigate adverse outcomes.

This paper explores how banks’ environmental, social, and governance (ESG) activities affect their lending during financial crises. We use a sample of European listed banks with available ESG scores from 2002 to 2020 and consider the global financial crisis of 2007–2009 and the European sovereign debt crisis of 2010–2012. We estimate a two-step system GMM dynamic panel data model and also address potential endogeneity with instrumental variable (IV) and difference-in-difference (DiD) estimations. We find that lending falls to a lesser extent for banks with higher ESG scores during crisis times. Our findings are robust to using alternative ESG rating providers. An investigation of the different potential channels shows that, during crises, banks more engaged in ESG activities are less affected in terms of credit risk, asset risk, and profitability. They also face a lower reduction in market funding, allowing them to downsize to a lesser extent during crises, and their deposit rates do not increase as much as in less ESG-engaged banks. A deeper investigation reveals that our findings mainly hold for banks focused on traditional lending and deposit activities and are essentially driven by the environmental pillar component of ESG scores and the global financial crisis of 2007–2009.

While government led bank capital infusions in US and other developed markets have been usually contingent an external shock or crisis episode, India presents a unique setting where significant capital infusions happen annually to stabilize the weak balance sheets of undercapitalized government owned public sector banks. Such “repeated” capital infusions can either better engender financial stability, given the timely government interventions; or create instability arising from possible moral hazard concerns. "Do such repeated government capital infusions lower banks’ financial risks and improve financial stability?” We shed light on the question through the lens of capital infusions in the Indian market. Based on the exhaustive sample of government capital infusions into public sector banks for the period 2008–18, we find robust evidence that capital infusions are associated with economically significant higher default, capital shortfall and network risks post-infusion, signaling a moral hazard problem, where treated banks may assume more risky investments.

This study examines the spillover effect of constituency statutes along the supply chain. We posit that the enactment of constituency statutes in customer firms’ incorporation states, by removing legal obstacles for customer firms to cater to non-shareholders’ interests, builds suppliers’ trust and cooperation. Consistent with the notion that constituency statutes entice greater trust from suppliers, we find that suppliers make more relationship-specific investments in the supply chain after the enactment of constituency statutes in customers’ states, indicating a greater commitment to the customer. We also show an improvement in customers’ corporate social responsibility performance in the post-constituency-statute period, thus substantiating the claim that the constituency statutes increase customers’ stakeholder orientation. Cross-sectionally, we find the positive effect of constituency statutes on supplier relationship-specific investments is attenuated if the customer and supplier have more repeated interactions in the past, whereas the effect is more pronounced if suppliers produce durable goods. Overall, we provide novel evidence on the spillover of constituency statutes along the supply chain.

We conduct an international study on the effect of climate policy uncertainty on the systemic risk of banks from G20 countries. We find that climate policy uncertainty is associated with lower bank systemic risk. This relation is more pronounced in countries with high innovation capacity, climate readiness, more systemically important banks, and a more competitive banking system. Climate-related information disclosure and sustainable investments are critical economic channels through which the effect of climate policy uncertainty works. Our findings alleviate the concern that climate transition risk may contribute to financial instability and provide practical implications for regulators to design climate transition policies.

In this paper we provide a framework to study the network topology of generalized forecast error variance decomposition (GFEVD) derived from multi-country, multi-variable time series models. Our dynamic variance decomposition network is based on a Bayesian Global Vector Autoregressive (GVAR) model, a suitable macroeconometric method to consider simultaneous multi-level interdependencies across variables. We demonstrate the usefulness of our methodology to analyze the network structure of shock propagation in longitudinal time series and, in particular: (a) the shortest paths of contagion; (b) the clusters of shock transmission; (c) the role of nodes in the risk transmission channels. We illustrate our method through an empirical application to a set of 12 European countries’ Industrial Production, Retail Trade and Economic Sentiment indices over the period 01/2000–11/2021.

There is ample empirical literature centering on the effectiveness of foreign exchange intervention (FXI). Given the mix of objectives and country-heterogeneity, the general lack of consensus thus far is no surprise. We shed light on this debate by conducting the first comprehensive meta-analysis in the FXI literature, with 279 reported effects that stem from 74 distinct empirical studies. We cover estimations conducted in 19 countries across five decades. Overall, our meta-survey reports an average depreciation of domestic currency of 1% and a reduction of exchange rate volatility of 0.6%, in response to a $1 billion US dollar purchase. Results are qualitatively confirmed but smaller in size under fixed and random-effect estimations. When narrowing in on different economic factors, we find that effects are magnified for cases consistent with the monetary trilemma (greater if financial openness and monetary independence are low). Effects are also larger in emerging than advanced economies, when banking crises remain mild, and when interventions are large in size and are announced.

Sri Lanka unilaterally defaulted on its external debt in April 2022, exposing its long-standing economic and financial vulnerabilities and igniting a series of inter-related multiple economic crises—fiscal, debt, currency, inflation, and balance of payments—as well as a vast socio-political upheaval. This paper analyses the economic crisis and its various dimensions to understand the sources of the crisis and draw policy implications. The role of fiscal balances and public debt in the crisis, along with debt sustainability, international sovereign bonds, liquidity crisis, and currency collapse, are analyzed. The root cause of Sri Lanka’s economic crisis was running persistent and large fiscal deficits, which were increasingly financed by unsustainable public debt, particularly foreign commercial borrowings. A substantial reduction and reprofiling of debt through restructuring of both domestic and foreign debt to ensure debt sustainability, meaningful fiscal policy reforms anchored by revenue increases and expenditure rationalization to reduce fiscal deficits, and deep growth-enhancing structural reforms are necessary for medium-term rescue and recovery and long-term growth and stability of Sri Lanka. The findings provide important policy lessons for other emerging markets and middle-income economies.

Banks in emerging market economies rely on cross-border interbank lending to financing firms in the real sector. By matching cross-border bank-to-bank loan level data with domestic bank-to-firm loan level data, and firm-level data, this paper shows that the sudden yield reversal observed during the 2013 Fed taper tantrum resulted in a substantial contraction of cross-border credit to banks in emerging markets that significantly reduced the supply of domestic corporate credit and increased loan rates. Results show that firms with an ex-ante high concentration of credit granted by exposed banks in the cross-border interbank lending market exhibited low bank credit and substantial real effects, including a decline in imports and exports. The results indicate that cross-border intra-group lending and domestic unsecured interbank funding contribute to smoothing the effects of sudden yield reversals on the financial intermediation. Overall, the results are consistent with the notion that the level of banks’ exposition in international credit markets contributes to global financial conditions’ transmission to the economy.

We present a quantitative model of deposit insurance to characterize the optimal levels of coverage for depositors and premiums raised from banks. Premiums contribute to a deposit insurance fund that lowers taxpayers’ resolution cost of bank failures. The key model tension is the policymaker’s dynamic tradeoff between building a fund to discourage moral hazard and insulate taxpayers from large fiscal shortfalls, and allowing banks to productively invest their deposits. We find that risk-adjusted premiums reduce moral hazard, enabling the policymaker to increase the share of covered deposits to total deposits by 12.5 percentage points and decrease the share of expected annual bank failures from 0.74% to 0.60%. The model predicts a fund-to-covered-deposits ratio that matches the data and declines in taxpayers’ income due to taxpayers’ risk aversion.
