Self-reinforcing effects between housing prices and credit

The financial crisis has brought the interaction between housing prices and household borrowing into the limelight of the economic policy debate. This paper examines the nexus of housing prices and credit in Norway within a structural vector equilibrium correction model (SVECM) over the period 1986q2–2008q4. The results establish a two way interaction in the long-run, so that higher housing prices lead to a credit expansion, which in turn puts an upward pressure on prices. Interest rates influence housing prices indirectly through the credit channel. Furthermore, households’ expectations about the future development of their own income as well as in the Norwegian economy have a significant impact on housing price growth. Dynamic simulations show how shocks are propagated and amplified. When we augment the model to include the supply side of the housing market, these effects are dampened.     

Early warning indicators and macro-prudential policies: a credit network agent based model

Credit network configurations play a crucial role in determining the vulnerability of the economic system. Following the network-based financial accelerator approach, we constructed an agent based model reproducing an artificial credit network that evolves endogenously according to the leverage choices of heterogeneous firms and banks. Thus, our work aims at defining both early warning indicators for crises and policy precautionary measures based on the endogenous credit network dynamics. The model is calibrated on a sample of firms and banks quoted in the Japanese stock-exchange markets from 1980 to 2012. Both empirical and simulated data suggest that credit and connectivity variations could be used as early warning measures for crises. Moreover, targeting banks that are central in the credit network in terms of size and connectivity, the capital-related macro-prudential policies may reduce systemic vulnerability without affecting aggregate output.     

国房地产市场金融加速器效应的实证研究

中国房地产市场近年来一直处于非理性繁荣状态,因此,中央政府陆续出台一系列房地产调控政策旨在挤出房地产泡沫,平抑其投资过热现象,从而实现宏观经济在金融危机后的软着陆。此外,央行不断上调存款准备金率和基准利率更是加重了仍处在调控政策消化阶段的房地产市场的下行预期。根据金融加速器理论,初始的外部冲击通过信贷市场的放大作用,最终将引发大幅度的市场波动,破坏实体经济的正常运行。房地产企业的高负债率和开发模式决定了房地产市场中金融加速器效应十分显著,尤其是在政策变动和楼市供求关系发生逆转的情况下,表现更为明显。最后提出了相应的政策建议．     

The role of banking regulation in an economy under credit risk and liquidity shock

This paper develops a Dynamic Stochastic General Equilibrium model which includes a financial sector to analyze the effects of liquidity shock and credit risk in the Brazilian economy. Banks use equity capital and deposits from agents to finance investments of the productive sector. The sources of financial frictions are default rate and liquidity shock, due to deposits withdrawn in advance. The banking supervisor injects liquidity in the deposit market. Using data for the Brazilian economy in the period from 1995 to 2009, the structural parameters are estimated by Bayesian methods. Impulse response functions are computed to describe the dynamic effects of exogenous shocks. The major results show that credit risk is pro-cyclical and default risk depends on structural features. The banking regulator is able to set up a policy to promote financial stability and efficiently reduce fluctuations in the output.     

Financial intermediation and real estate prices impact on business cycles: A Bayesian analysis

How do financial intermediation and real estate prices impinge on the business cycle? I develop a two-sector stochastic general equilibrium model with financial intermediation and real estate collateral to assess the impact of financial conditions and land prices on aggregate fluctuations. I estimate the model with Bayesian methods using a novel data set that includes U.S. macro and financial variables during the period 1975–2010. The results from the estimated model show that financial conditions have a sizable effect on the variability of investment spending, while productivity shocks are the main source of consumption fluctuations. Specifically, on the macro side, (1) financial shocks explain about three quarters of investment spending variability and one third of the variance in hours worked. On the financial side, (2) financial shocks explain most of the variability in land prices, credit spread, and aggregate net worth of the financial sector. The model also accounts for observed unconditional moments of macro and financial variables. Our quantitative results are suggestive of the impact of diverse sources of financial instability, and as such relevant for macro prudential policy analysis.     

Lending attitude as a financial accelerator in a credit network economy

In existing literature, commercial banks are often considered mere financial intermediaries that facilitate the flow of credit in an imperfect credit market. However, as demonstrated in the history of financial instability, the behavior of financial institutions plays an important role. This paper examines how lenders’ attitudes affect macroeconomic performance. In our analysis, the economy is composed of multiple borrowers (firms) and one lender (bank). Each borrower is directly connected to the lender through its credit contract. At the same time, each borrower is indirectly connected to all the other borrowers within the credit network. Using this model, we execute computer simulations to examine the economic consequences of lending attitudes. The results of the simulations demonstrate that the bank’s lending attitude functions as a financial accelerator; that is, it significantly affects the dynamics of the economic system through the credit network. Consequently, the same level of exogenous shock generates completely different outcomes depending on the different lending attitudes. The results also show that there exists an optimal lending attitude that leads to high economic growth and a stable growth path.     

Dynamics and equilibrium in a structural model of wide‐body commercial aircraft markets

This paper develops and estimates a dynamic equilibrium model of the market for new and used commercial aircraft. The model is estimated by maximum simulated likelihood using data on wide‐body aircraft owners and prices for transactions occurring 1978‐1997. The importance of explicitly modeling dynamics and equilibrium in new and used markets for durable goods is illustrated in two counterfactual experiments. Estimates of the structural model are used to show that implementing an investment tax credit not only increases demand for new wide‐body aircraft by the airlines that receive the tax credit, but also increases the number of new wide‐body aircraft owned by airlines not directly affected by the policy. Further, the model indicates that a policy which improves the efficiency of secondary markets for used wide‐body aircraft will also stimulate demand for new wide‐body aircraft.

Financial Constraints: Routine Versus Cutting Edge R&D Investment

We analyze financial constraints on R&D, where we account for heterogeneity among investments that has been neglected in previous literature. According to economic theory, investments should be distinguished by their degree of uncertainty, e.g. routine R&D versus cutting‐edge R&D. Financial constraints should be more binding for cutting‐edge R&D than for routine R&D. Using panel data we find that R&D spending of firms devoting a significant fraction of R&D to cutting‐edge projects is curtailed by credit constraints while routine R&D investments are not. This has important policy implications with respect to the distribution of R&D subsidies in the economy.

The implications of financial frictions and imperfect knowledge in the estimated DSGE model of the U.S. economy

In this paper, I study how alternative assumptions about expectation formation can modify the implications of financial frictions for the real economy. I incorporate a financial accelerator mechanism into a version of the Smets and Wouters (2007) DSGE framework and explore the properties of the model assuming, on the one hand, complete rationality of expectations and, alternatively, several learning algorithms that differ in terms of the information set used by agents to produce the forecasts. I show that the implications of the financial accelerator for the business cycle may vary depending on the approach to modeling the expectations. The results suggest that the learning scheme based on small forecasting functions is able to amplify the effects of financial frictions relative to the model with Rational Expectations. Specifically, I show that the dynamics of real variables under learning is driven to a significant extent by the time variation of agents’ beliefs about financial sector variables. During periods when agents perceive asset prices as being relatively more persistent, financial shocks lead to more pronounced macroeconomic outcomes. The amplification effect rises as financial frictions become more severe. At the same time, a learning specification in which agents use more information to generate predictions produces very different asset price and investment dynamics. In such a framework, learning cannot significantly alter the real effects of financial frictions implied by the Rational Expectations model.     

Do credit squeezes influence firm survival? An empirical investigation of China

This paper analyses the effect of a “credit squeeze” policy that was set by the Chinese government in 2007, increasing the strictness for firm-level bank loans. We adopt the difference-in-difference (DID) model to compare the survival rate change before and after the policy was implemented. We further explore the mechanism behind how the “credit squeeze” policy reduced the probability of firms surviving the market from perspectives such as financial constraints and ownership structures. The “credit squeeze” policy significantly increased firms’ operating costs and lowered firms’ productivity. In addition, we find that the zombie firm phenomenon existing in state-owned enterprises has a large impact on our estimation. Our results provide practical policy implications regarding the compromise between systematic debt risk and firm survival.     

Do credit market imperfections justify a central bank׳s response to asset price fluctuations?

Do credit market imperfections justify a central bank׳s response to asset price fluctuations? This study addresses this question from the perspective of equilibrium determinacy. In the model we use, prices are sticky and the working capital of firms is subject to asset values because of a lack of commitment. If credit market imperfections exist to a small degree, the Taylor principle is a necessary and sufficient condition for equilibrium determinacy, and monetary policy response to asset price fluctuations is good from the perspective of equilibrium determinacy. However, if credit market imperfections exist to a large degree such that the collateral constraint is binding, then the Taylor principle no longer guarantees equilibrium determinacy, and monetary policy response to asset price fluctuations becomes a source of equilibrium indeterminacy. We find that the existence of credit market imperfections makes it unsuitable to initiate a monetary policy response to deal with asset price fluctuations. We also find that reductions in credit market imperfections can enlarge the indeterminacy region of the model parameters.     

The impact of credit supply shocks and a new Financial Conditions Index based on a FAVAR approach

This paper investigates the impact of credit supply shocks on the macroeconomy and estimates a new financial conditions index. We calculated two credit supply factors using a time-varying parameter FAVAR model. The first factor is identified as the willingness to lend, while the second factor is the lending capacity. The impact of these two types of shocks and their changes over time is examined using Hungarian data. The two types of lending shocks affect macro variables rather differently: a positive lending capacity shock (in a banking system mostly owned by non-residents) influences GDP through a decrease in country risk and the easing of monetary policy, while willingness to lend primarily increases lending activity. The two financial shocks also differ in terms of their evolution over time: deviations from the average in the impact of a willingness to lend shock usually occur for short periods of time and are of a small degree between the various quarters. However, in the case of lending capacity, certain trends can be observed: before the crisis, the stability of the banking system played an increasing role in country risk, whereas after 2008 it appears that monetary policy paid increasing attention to financial stability. Finally, a new type of financial conditions index is quantified based on our estimates, which measures the impact of the banking system’s lending activity on GDP growth.     

The impact of political connections on government bailout: the 2008 credit crunch in the United States

Why is there so little money in contributions to political action committees (PAC) in United States’ politics? While there may be several explanations for this puzzle, we consider corporate PAC contributions as an insurance-like instrument that induces firms’ expectations of safeguard at times of grave need, with the 2008 credit crunch as a case in point. Given the unlikely occurrence of a credit crunch, few financial firms invest in PAC contributions. However, we find firms that make PAC contributions may gain ex ante benefits of corporate PACs as protection from financial distress by undertaking profitable but risky projects that later become illiquid assets while requiring the bailout money during the 2008 credit crunch. We also find that both consistent PAC investments over election cycles and subsequent lobbying activity to corporate PACs further allow firms to utilize their political ties as safeguard and demand additional bailout money. Our instrumental variable analysis confirms that firms with prior experience in political investments are found to enhance the likelihood and effectiveness of PAC contributions and related political investments.     

Credit rationing when banks are funding constrained

Credit crunches, such as in the recent financial crisis, generally occur when banks are themselves funding constrained. We use this observation to repair the workhorse Stiglitz–Weiss model of credit rationing. Recent research has invalidated the distributional assumption on which that model is based. This paper shows that by adding the assumption that banks are capacity constrained, Stiglitz–Weiss rationing can occur again. It discusses how this finding can be related to the current policy debates on bank funding and credit provision.     

Lessons from a century of FED policy: Why monetary and credit policies need rules and boundaries

Wide operational and financial independence given to monetary and credit policies subjects the Federal Reserve to incentives detrimental for macroeconomic and financial stability. The absence of a monetary policy rule created go-stop incentives that produced inefficient volatility of both inflation and unemployment during the Great Inflation. Fed credit policy has undergone massive “mission creep” since the Fed was established. Being debt-financed fiscal policy, Fed credit policy beyond ordinary temporary lending to solvent depositories creates friction with the fiscal authorities and jeopardizes the Fed׳s independence. An ambiguous boundary of expansive Fed credit policy creates expectations of Fed accommodation in financial crisis—that blunts the incentive of private entities to take protective measures beforehand (to shrink counter-party risk and reliance on short-term finance, and build up equity capital) and blunts the incentive of the fiscal authorities to prepare procedures in advance to act systematically in times of credit turmoil. These points are illustrated with reference to the 2007–09 financial crisis. Part of the problem is that the independent Fed does not have the same incentive as the 19th century Bank of England to follow Bagehot׳s Rule. The paper concludes with a set of principles to preserve a workable, sustainable division of responsibilities between the independent central bank and the fiscal authorities.     

Macroeconomic and financial stability in a monetary union: The case of Lithuania

In this paper, we study the implications of macroprudential policies in a monetary union for macroeconomic and financial stability. For this purpose, we develop a two-country monetary union new Keynesian general equilibrium model with housing and collateral constraints, to be calibrated for Lithuania and the rest of the euro area. We consider two different scenarios for macroprudential policies: one in which the ECB extends its goals to also include financial stability and a second one in which a national macroprudential authority uses the loan-to-value ratio (LTV) as an instrument. The results show that both rules are effective in making the financial system more stable in both countries, and especially in Lithuania. This is because the financial sector in this country is more sensitive to shocks. We find that an extended Taylor rule is indeed effective in reducing the volatility of credit, but comes with a cost in terms of higher inflation volatility. The simple LTV rule, on the other hand, does not compromise the objective of monetary policy. This reinforces the “Tinbergen principle”, which argues that there should be two different instruments when there are two different policy goals.     

The impact of credit and fiscal policy under a liquidity trap

This study examines the interaction of non-conventional credit policy and fiscal policy when adverse financial conditions drive the economy to a deep contraction and conventional monetary policy becomes ineffective as the policy interest rate reaches its effective lower bound. Consistent with other studies, under counter-cyclical financial intermediation costs, credit easing policies aimed at reducing credit spread ameliorate the response of the economy and lead to a faster recovery. More importantly, I find that expansionary fiscal policy during an episode of liquidity trap is associated with a large multiplier effect that prevents an otherwise deeper and longer recession. Moreover, the large impact of expansionary fiscal policy is maintained even if credit policy is already in place.     

绿色信贷政策能够抑制企业的风险承担吗？

绿色信贷是桥接金融信用与环保的关键纽带和资源配置的重要抓手。基于2012年银监会颁布《绿色信贷指引》的外生冲击，使用双重差分(DID)探讨绿色信贷政策对企业风险承担的影响。首先，基准回归表明绿色信贷抑制了绿色信贷限制企业的风险承担水平，但政策影响的时滞性和企业的策略性应对使得政策颁布两年后抑制作用才不断增强。其次，融资约束和投资惩罚的中介机制表明，融资约束和投资支出在绿色信贷政策与企业风险承担之间存在遮掩效应，进一步抑制了企业风险承担水平。最后，信息效应和环境规制倒逼效应的调节机制表明绿色信贷政策影响存在非对称性。
