Financial Exposure and the International Transmission of Financial Shocks

This paper analyzes the transmission mechanism of banking sector shocks in an international real business cycle model with heterogeneous bank sizes. We examine to what extent the financial exposure of the banking sector affects the transmission of foreign banking sector shocks. In our model, the more exposed domestic banks are to the foreign economy via lending to foreign firms, the greater are the spillovers from foreign financial shocks to the home economy. The model highlights the role of openness to trade and the dynamics of the terms of trade in the international transmission mechanism of banking sector shocks: spillovers from foreign banking sector shocks are greater the more open the home economy is to trade and the less the terms of trade respond to foreign shocks.     

The Interaction between Capital Requirements and Monetary Policy

The interaction between capital requirements and monetary policy is assessed by means of simple rules in a dynamic general equilibrium model featuring a banking sector. In “normal” times, when economic dynamics are driven by supply shocks, an active use of capital requirements generates modest benefits in terms of volatility of the target variables compared to the case in which only the central bank carries out stabilization policies. The lack of cooperation between the two policymakers may result in excessive volatility of the monetary policy rate and capital requirements. The benefits of introducing capital requirements become sizeable when financial shocks, which affect the supply of loans, are important drivers of economic dynamics; the availability of capital requirements as a policy tool yields a significant gain in terms of macroeconomic stabilization, regardless of the type of interaction between monetary and capital requirements policies.     

Financial friction in an emerging economy

The objective of this study is to evaluate the role of the frictional domestic credit market in an emerging country by using a small-open-economy DSGE model with a banking sector. The calibration results show that the financial friction does not significantly influence the macroeconomic effects of the shocks to the domestic productivity, foreign interest rate and export demand. We also evaluate whether and how the trade and financial openness can influence the effects of the domestic financial shocks that in turn affect the supply of loans in the credit market. We show that greater trade and financial openness can reduce the macroeconomic impacts of the domestic financial distress. Under a more open international capital market, the capital outflow caused by the domestic financial shock does not lead to drastic exchange rate variation. This helps dampen the adverse effects of the financial distress on the economy.     

Credit crunch in a small open economy

We construct an open-economy DSGE model with a banking sector to analyze the impact of the recent credit crunch on a small open economy. In our model the banking sector operates under monopolistic competition, collects deposits and grants collateralized loans. Collateral effects amplify monetary policy actions, interest rate stickiness dampens the transmission of interest rates, and financial shocks generate non-negligible real and nominal effects. As an application we estimate the model for Poland-a typical small open economy. According to the results, financial shocks had a substantial, though not overwhelming, impact on the Polish economy during the 2008/09 crisis, lowering GDP by approximately 1.5 percent.     

Shadow Banks and Macroeconomic Instability

We develop a macroeconomic model in which commercial banks can offload risky loans to a “shadow” banking sector, and financial intermediaries trade in securitized assets. The model can account both for the business cycle comovement between output, traditional bank, and shadow bank credit, and for the behavior of macroeconomic variables in a liquidity crisis centered on shadow banks. We find that following a liquidity shock, stabilization policy aimed solely at the market in securitized assets is relatively ineffective.     

Durable Goods,Investment Shocks,and the Comovement Problem

Sticky‐price models suggest that capital investment shocks are an important driver of business cycle fluctuations. Despite quantitative importance in explaining business cycles, a comovement problem emerges because the shocks generate intertemporal substitution effects away from consumption toward investment. This paper resolves the problem by extending the standard sticky‐price model to a two‐sector model with consumer durable services. When durable goods are used as investment in capital and consumer durables, positive capital investment shocks also generate intratemporal substitution effects away from consumer durable services toward nondurable consumption that dominates intertemporal effects. Consequently, consumption increases, and the comovement problem is resolved.     

Countercyclical Bank Capital Requirement and Optimized Monetary Policy Rules

Using BoC-GEM-Fin, a large-scale dynamic stochastic general equilibrium (DSGE) model with real, nominal, and financial frictions featuring a banking sector, we explore the macroeconomic implications of various types of countercyclical bank capital regulations. Results suggest that countercyclical capital requirements have a significant stabilizing effect on key macroeconomic variables, but mostly after financial shocks. Moreover, the bank capital regulatory policy and monetary policy interact, and this interaction is contingent on the type of shocks that drive the economic cycle. Finally, we analyze loss functions based on macroeconomic and financial variables to arrive at an optimal countercyclical regulatory policy in a class of simple implementable Taylor-type rules. Compared to bank capital regulatory policy, monetary policy is able to stabilize the economy more efficiently after real shocks. On the other hand, financial shocks require the regulator to be more aggressive in loosening/tightening capital requirements for banks, even as monetary policy works to counter the deviations of inflation from the target.     

Dynamics of Banks' Capital Accumulation

We construct a dynamic neoclassical model of banking capital where the dynamics are governed by the process of financial capital accumulation and credit risk realizations in a structure where stylized banking characteristics are maintained. This is aimed at focusing on how the profit‐maximizing capital ratio of banks evolves and how it reacts to exogenous shocks particularly so during periods of prolonged downturn of the economy. We examine impulse responses of our model to credit risk shock, business cycle shock, and monetary policy shock. The convergence of financial capital to its optimal level is also explored.     

Intersectoral Labor Immobility,Sectoral Comovement,and News Shocks

Sectoral comovement of output and hours worked is a prominent feature of business cycle data. However, most two‐sector neoclassical models fail to generate this sectoral comovement. We construct and estimate a two‐sector neoclassical Dynamic Stochastic General Equilibrium (DGSE) model generating sectoral comovement in response to both anticipated and unanticipated shocks. The key to our model's success is a significant degree of intersectoral labor immobility, which we estimate using data on sectoral hours worked. Furthermore, we demonstrate that imperfect intersectoral labor mobility provides a better explanation for the sectoral comovement than an alternative model emphasizing the role of labor‐supply wealth effects.     

Bank-to-bank lending channel and the transmission of bank liquidity shocks: Evidence from France

Good liquidity is essential for the banking system to function properly and supply credit to the real sector. However, several banks all over the world face large shocks to their liquidity supply due to numerous factors. This study contributes to the literature on the transmission of liquidity shocks by investigating the bank-to-bank lending behavior of French banks during the global financial crisis (2008 and 2009). In addition, we examine the factors strongly influencing the liquidity of the interbank deposits market. First, using a fixed-effects model on a sample of 85 French banks for the period from 2005 to 2010, we find that the deposits channel plays an important role in the transmission of liquidity shocks across the banking system. Second, we use difference-in-difference methodology to study the effects of liquidity shock on bank lending. Our results show that French banks reduced their bank-to-bank lending significantly during the financial crisis period. Moreover, our results suggest that the reduction could have been due to deposit activities.     

Supply of bank loans and business debts: A view from historical bankruptcy cases

As bank loans fell in the 2008 crisis, business bankruptcy increased. To study how bank loans affect business balance sheets and bankruptcy, we use new data on bankrupt businesses in Missouri between 1898 and 1942. We confirm that when banks curtail loans, courts see more bankruptcies among businesses with high exposure to bank debt. To reduce real volatility, policy‐makers can set tough bank liquidity requirements in the upswing of business cycle but allow weaker requirements in the downswing. We also find that between 1914 and 1933, businesses in St. Louis were more sensitive to changes in bank loans than businesses in Kansas City, probably due to the tight monetary policy conducted by the conservative St. Louis Fed. The Glass‐Steagall Act weakened the relationship between bank loans and business debt structure. The takeaway is that lender‐of‐last‐resort practices stabilize both the financial sector and the real economy.     

Does bank lending affect output? Evidence from the U.S. states

This paper uses a panel of state-level data to test whether changes in bank loan supply affect output. Since the U.S. states are small open economies with fixed exchange rates, state-specific shocks to money demand are automatically accommodated, leading to changes in lending if banks rely on deposits as a source of funding. Using these shocks as an instrumental variable, I find that shocks to money demand have large and statistically significant effects on the supply of bank loans, but loans have small, often negative and statistically insignificant effects on output.

Multinational banking and the international transmission of financial shocks: Evidence from foreign bank subsidiaries

Using bank-level data on 368 foreign subsidiaries of 68 multinational banks in 47 emerging economies during 1994–2008, we present consistent evidence that internal capital markets in multinational banking contribute to the transmission of financial shocks from parent banks to foreign subsidiaries. We find that internal capital markets transmit favorable and adverse shocks by affecting subsidiaries’ reliance on their own internal funds for lending. We also find that the transmission of financial shocks varies across types of shocks; is strongest among subsidiaries in Central and Eastern Europe, followed by Asia and Latin America; is global rather than regional; and becomes more conspicuous in recent years. We also explore various conditions under which the international transmission of financial shocks via internal capital markets in multinational banking is stronger, including the subsidiaries’ reliance on funds from their parent bank, the subsidiaries’ entry mode, and the capital account openness and banking market structure in host countries.     

Financial Innovation,Basel Accord III,and Bank Value

I examine how financial innovation and Basel III capital requirements in Taiwan respond differently to banking crises and market competition. My panel data set comprises data from thirty-four banks for 2000-2012. I find a significant negative relationship between derivatives and the value of a bank and significant positive relationships among the capital adequacy ratio, bank-specific variables, and the value of a bank. Larger bank size and operational diversification tend to be positively associated with a bank's value, the holding of a relatively high amount of capital requirements, and nonperforming loans that are large. The latter result may simply reflect the scale of economy and improvement of efficiency in terms of financial innovation in the banking sector.     

English commercial bank liquidity, 1860-1913

This article presents new half-yearly time series for the asset ratios of commercial banks in England and Wales, 1860-1913. The series reveal new evidence on the nature of the banks' business and are, therefore, relevant to the debate on the role of banks in British economic development. The new estimates are used to examine trends and short-term changes in bank liquidity. Analysis is concerned with the changing stability of bank asset structure and with substitutability across different asset ratios. The main finding is of a sharp, long-term increase in liquidity and a concomitant decline in bank credit to the non-bank, private sector. The article also highlights the significance of short-term shocks to the trend increase in bank liquidity. The new findings are supportive of the argument that, over time, English banks became less involved with the non-bank private sector. In general, the results confirm that the English and Welsh bank asset structure became more liquid over time. However, no detailed breakdown of bank loans to the non-bank, private sector (for example, between business loans and personal loans), is available for this period. Moreover, the current study offers no evidence as to the trend in financial provision to the business sector from institutions other than the commercial banks. Nevertheless, the results are clear in showing a strong upward trend in commercial bank liquidity and a relative decline in private sector credit provision by the commercial banks.     

Monetary policy, taxes, and the business cycle

This paper analyzes the interaction of inflation with the tax code and its contribution to aggregate fluctuations. We find significant effects operating through the tax on realized nominal capital gains. A tax on nominal bond income magnifies these effects. Our innovation is to combine monetary policy shocks with non-indexed taxes in a model where the central bank implements policy using an interest rate rule. Monetary policy had important effects on the behavior of the business cycle before 1980 because policymakers did not exert effective control over inflation. Monetary policy reform around 1980 led to better control, and with more stable inflation, the effect of the interaction between monetary policy and the nominal capital gains tax has become negligible.     

Monetary Policy,Bank Lending,and the Risk‐Pricing Channel

This paper identifies a monetary policy channel through the risk pricing of bank debt in the market for jumbo certificates of deposit (jumbo CDs). Adverse policy shocks increase debt holder perceptions of bank default, increasing the risk premia for some banks, thereby decreasing their external funding of loans. The results show that contractionary policy increases the sensitivity of jumbo‐CD spreads to leverage and asset risk for small banks, and to leverage for large banks. The results also show a distributional and aggregate effect on banking system jumbo CDs and total loans, producing a risk‐pricing (or market discipline) channel. This channel has implications for monetary and regulatory policies, and financial stability.     

The effect of the interbank network structure on contagion and common shocks

This paper proposes a dynamic multi-agent model of a banking system with central bank. Banks optimize a portfolio of risky investments and riskless excess reserves according to their risk, return, and liquidity preferences. They are linked via interbank loans and face stochastic deposit supply. Comparing different interbank network structures, it is shown that money-centre networks are more stable than random networks. Evidence is provided that the central bank stabilizes interbank markets in the short run only. Systemic risk via contagion is compared with common shocks and it is shown that both forms of systemic risk require different optimal policy responses.     

Corporate Governance and Corporate Financing and Investment during the 2007‐2008 Financial Crisis

We examine the impact of the 2007‐2008 financial crisis on nonfinancial firms’ financing and investment activities and the role of corporate governance in alleviating the adverse consequences of the external capital supply shock. Employing a difference‐in‐differences research design, we find that better governance mitigates the disruption caused by the bank credit supply shock to firms’ financing and investment activities. A variety of robustness tests suggest that our findings are unlikely to be driven by an endogeneity problem. We obtain similar results when we extend the sample period to include the delayed spillover from the banking sector to other capital market sectors.
