The Great Moderation was accompanied by an increase in financial volatility. We explore the sources of these divergent patterns in volatilities by estimating a model with time‐varying financial rigidities subject to structural breaks in the size of shocks, the monetary policy rule coefficients, and the average size of the financial rigidity. Institutional changes are key in accounting for the Great Moderation and in shaping the transmission mechanism of financial shocks. The increase in financial volatilities is accounted for by larger financial shocks, but the vulnerability of the economy to these shocks is significantly alleviated by the estimated changes in institutions.  相似文献

Recent studies identify Marginal Efficiency of Investment (MEI) shocks as important drivers of the business cycle. However, Dynamic Stochastic General Equilibrium (DSGE) models struggle to explain macroeconomic comovements between consumption and the key real variables after a MEI shock. Moreover, engaging in tax evasion practices is often an answer to financial constraints, which have been recognized as important determinants of cyclical fluctuations as well. We use a medium-scale New Keynesian DSGE model, that combines tax evasion with financial frictions, to simulate a MEI shock. We show that entrepreneurial tax evasion can solve the comovement problem to a fair extent.  相似文献

This article examines the role of the extensive and intensive margins of labor input in the context of a business cycle model with a financial friction. We document significant variation in the hours worked per worker for many emerging-market economies using manufacturing data. Both employment and hours worked per worker are positively correlated with each other and with output. We show that a search-theoretic context in a small open-economy model requires a small wealth effect to explain these regularities at the expense of a smaller wage response. On the other hand, introducing a financial friction in the form of a working capital requirement can explain the observed movements of labor market variables such as employment and hours worked per worker, as well as other distinguishable business cycle characteristics of emerging economies. These include highly volatile and cyclical real wages, labor share, and consumption.  相似文献

We probe the scope for reacting to house prices in simple and implementable monetary policy rules, using a New Keynesian model with a housing sector and financial frictions on the household side. We show that the social‐welfare‐maximizing monetary policy rule features a reaction to house price variations, when the latter are generated by housing demand or financial shocks. The sign and size of the reaction crucially depend on the degree of financial frictions in the economy. When the share of constrained agents is relatively small, the optimal reaction is negative, implying that the central bank must move the policy rate in the opposite direction with respect to house prices. However, when the economy is characterized by a sufficiently high average loan‐to‐value ratio, then it becomes optimal to counter house price increases by raising the policy rate.  相似文献

Emerging economies are characterized by higher variability of consumption and real wages relative to output and a strongly countercyclical current account. A small open economy model with search‐matching frictions and countercyclical interest rate shocks can account for these regularities. Search‐matching frictions affect permanent income, and increase future employment uncertainty, heightening workers' incentives to save and generating a greater response of consumption and the current account. The greater consumption response feeds into larger fluctuations in workers' willingness to work, while interest rate shocks lead to variations in firms' willingness to hire; both of these outcomes contribute to highly variable wages.  相似文献

The paper extends a standard two‐country international real business cycle model to include financial intermediation by banks of loans and government bonds. The paper contributes an explanation for both the United States relative to the Euro‐area, and the United States relative to China, of cross‐country correlations of loan rates, deposit rates, and the loan premia. It shows a type of financial retrenchment for the United States relative to both Europe and China following a negative bank productivity shock, such as during the 2008 crisis. After 2008, results suggest that the Euro‐area has been more financially integrated with the United States, and China less financially integrated.  相似文献

We construct a dynamic macro model to incorporate financial frictions and investment delay. Investment is undertaken by entrepreneurs who face liquidity frictions in the equity market and a collateral constraint in the debt market. After calibrating the model to the U.S. data, we quantitatively examine how aggregate activity is affected by a shock to equity liquidity and a shock to entrepreneurs' borrowing capacity. We then analyze the effectiveness of government interventions in the asset market after such financial shocks. In particular, we compare the effects of government purchases of private equity and of private debt in the open market. In addition, we examine how these effects of government interventions depend on the option to delay investment.  相似文献

This paper studies how the process of reallocation of credit across firms behaves before and after financial crises. Applying the methodology typically used for measuring job reallocation, we track credit reallocation across Korean firms for over three decades (1980–2012). The credit boom preceding the 1997 crisis featured a slowdown of credit reallocation. After the crisis and the associated reforms, the creditless recovery (deleveraging) masked a dramatic intensification and increased procyclicality of credit reallocation. The findings suggest that the intensification of reallocation was efficiency‐enhancing.  相似文献

We provide robust evidence that news shocks about future investment‐specific technology (IST) constitute a significant force behind U.S. business cycles. Positive IST news shocks induce comovement, that is, raise output, consumption, investment, and hours. These shocks account for 70% of the business cycle variation in output, hours, and consumption, and 60% of the variation in investment, and have played an important role in 9 of the last 10 U.S. recessions. Our findings provide strong support for shifting focus to IST news shocks when investigating the role of news in driving U.S. business cycles.  相似文献

A growing literature considers the impact of uncertainty using SVAR models that include proxies for uncertainty shocks as endogenous variables. In this paper, we consider the impact of measurement error in these proxies on the estimated impulse responses. We show via a Monte Carlo experiment that measurement error can result in attenuation bias in impulse responses. In contrast, the proxy SVAR that uses the uncertainty shock proxy as an instrument does not suffer from this bias. Applying this latter method to the Bloom (2009) data set results in impulse responses to uncertainty shocks that are larger in magnitude and more persistent than those obtained from a recursive SVAR.  相似文献

We present a DSGE model where firms optimally choose among alternative instruments of external finance. The model is used to explain the evolving composition of corporate debt during the financial crisis of 2008–09, namely, the observed shift from bank finance to bond finance, at a time when the cost of market debt rose above the cost of bank loans. We show that the flexibility offered by banks on the terms of their loans and firms' ability to substitute among alternative instruments of debt finance are important to shield the economy from adverse real effects of a financial crisis.  相似文献

This paper introduces a two-period monetary general equilibrium model with proportional transaction costs on nominal and inflation-indexed bonds. This paper demonstrates that financial innovation on indexed bonds causes equilibrium interest rates of the nominal bond to increase when agents have precautionary saving motives. This result implies that ignoring precautionary motives would underestimate savers' welfare gain and overestimate borrowers' welfare gain from innovation on indexed bonds.  相似文献

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.  相似文献

I use a financial accelerator model to study interest and prices under boom–busts driven by changes in expectations about total factor productivity (TFP) and credit. I show that inflation falls in the boom phase of the TFP episode and then recovers during the bust, yet rises in the boom phase of the credit episode and then falls during the bust. Furthermore, for both episodes, the overaccumulation of debt relative to capital during the boom is critical for the busts since it implies a fall in credit worthiness. Finally, I show that stricter inflation targeting reduces inefficiencies in all instances but the boom phase of the TFP episode.  相似文献

We use several U.S. and euro‐area surveys of professional forecasters to estimate a dynamic factor model of inflation featuring time‐varying uncertainty. We obtain survey‐consistent distributions of future inflation at any horizon, both in the U.S. and the euro area. Equipped with this model, we propose a novel measure of the anchoring of inflation expectations that accounts for inflation uncertainty. Our results suggest that following the Great Recession, inflation anchoring improved in the United States, while mild de‐anchoring occurred in the euro area. As of our sample end, both areas appear to be almost equally anchored.  相似文献

Three themes connecting housing and the macroeconomy are discussed. First, evidence is presented for the property market as one of the drivers of U.S. consumer price inflation. Second, key drivers of house prices are explained to account for the remarkable diversity of international experience. Finally, three potential links between housing, credit, and the financial accelerator are discussed. These are the consumption channel, the investment channel, and feedback between bad loans and risk‐spreads via the financial system—and how institutional differences between countries can explain the presence, absence and magnitudes of these linkages.  相似文献

This paper estimates a two‐country model with a global bank, using U.S. and euro area (EA) data. Empirically, a model version with a bank capital requirement outperforms a structure without such a constraint. A loan loss originating in one country triggers a global output reduction. Banking shocks matter more for EA macro variables than for U.S. real activity. Banking shocks account for about 2–5% of the unconditional variance of U.S. GDP and for 3–14% of the variance of EA GDP. During the 2007–09 recession, banking shocks accounted for about 15% of the fall in U.S. and EA GDP, and for more than a third of the fall in EA investment and employment.  相似文献

Several countries in Central, Eastern, and Southeastern Europe used a rich set of prudential instruments during the recent credit and housing boom and bust cycles. We construct a comprehensive database of these policy measures covering 16 countries at a quarterly frequency. We use this database to investigate whether the policy measures had an impact on housing price inflation. The measures that appeared to be effective were capital measures (minimum capital adequacy ratio, maximum ratio of lending to households to share capital) and nonstandard liquidity measures (marginal reserve requirements (MRRs) on foreign funding, MRRs linked to credit growth).  相似文献

A house price boom occurred simultaneously in the United States and in a number of European countries from 2003 to 2007, accompanied in each case by an expansion in housing finance. This article considers the role of financial innovation along with incomplete markets in these cycles.  相似文献

Some implications of e-Commerce financial services firms are becoming clear. The web drives transparency, and increases the information endowment of all market participants. It is harder to manipulate customers' behavior, or to overcharge them. Transparency drives differential pricing. Not all customers can or should be charged the same prices. Transparency reduces the viability of cross-subsidies between customers can or between products. The differential pricing enabled by the web transforms distribution channels, and enables direct distribution and alternative forms of distribution. Some intermediateraries may be bypassed altogether, while others may rapidly lose their best, most profitable, and previously most loyal customers.  相似文献
