REAL ESTATE CYCLES, ASSET REDISTRIBUTION, AND THE DYNAMICS OF A CRISIS

In this paper, I explore the dynamics of real estate market fluctuations and business cycle co-movements in a neoclassical setting. Applying a dynamic stochastic general equilibrium model of collateral constraints with asset reallocation to Japan, I find that public policy shocks account well for the business cycle dynamics. In particular, taxes on land holdings of households mimic the impact of a housing preference shock, and if volatile enough, can trigger large asset price fluctuations. However, in the absence of volatility, the impact on prices is intrinsically linked to the persistence of shocks. Dependence on fixed assets such as real estate to secure collateral-based financing significantly amplifies the effect of initial shocks on the real macro aggregates. The financial accelerator works through the “redistribution channel,” shifting a large fraction of the collateral between constrained and unconstrained agents in response to an external stimuli.

Sentiments, financial markets, and macroeconomic fluctuations

This paper studies how financial information frictions can generate sentiment-driven fluctuations in asset prices and self-fulfilling business cycles. In our model economy, exuberant financial market sentiments of high output and high demand for capital increase the price of capital, which signals strong fundamentals of the economy to the real side and consequently leads to an actual boom in real output and employment. The model further derives implications for asymmetric nonlinear asset prices and for economic contagion and co-movement across countries. In the extension to the dynamic overlapping generations (OLG) setting, our model demonstrates that sentiment shocks can generate persistent output, employment, and business cycle fluctuations, and it offers some new implications for asset prices over business cycles.

Solving OLG Models with Many Cohorts, Asset Choice and Large Shocks

The paper presents a computationally efficient method to solve overlapping generations models with asset choice. The method is used to study an OLG economy with many cohorts, up to 3 different assets, stochastic volatility, short-sale constraints, and subject to rather large technology shocks. On the methodological side, the main findings are that global projection methods with polynomial approximations of degree 3 are sufficient to provide a very precise solution, even in the case of large shocks. Globally linear approximations, in contrast to local linear approximations, are sufficient to capture the most important financial statistics, including not only the average risk premium, but also the variation of the risk premium over the cycle. However, global linear approximations are not sufficient to reliably pin down asset choices. With a risk aversion parameter of only 4, the model generates a price of risk, measured as the Sharpe ratio, that is almost half of what it is for US stocks. However, the asset price fluctuations and the equity premium are much smaller than in US data.

Liquidity and asset prices in a monetary model with OTC asset markets

We study how asset prices are affected by the amount of liquidity that is available in over-the-counter asset markets where dealers post prices and quantities at which they are willing to buy and sell assets. We find that higher levels of market liquidity lead to higher asset prices and lower bid–ask spreads. Hence, an increase in inflation—which lowers market liquidity—increases asset returns and decreases asset prices. When agents' immediate consumption needs are stochastic, asset prices will fluctuate even though asset fundamentals are unchanging. The fluctuations in asset prices reflect the stochastic availability of market liquidity that results from agents' changing consumption opportunities.

Loss Aversion, Adaptive Beliefs, and Asset Pricing Dynamics

We study asset pricing dynamics in artificial financial markets model. The financial market is populated with agents following two heterogeneous trading beliefs, the technical and the fundamental prediction rules. Agents switch between trading rules with respect to their past performance. The agents are loss averse over asset price fluctuations. Loss aversion behaviour depends on the past performance of the trading strategies in terms of an evolutionary fitness measure. We propose a novel application of the prospect theory to agent-based modelling, and by simulation, the effect of evolutionary fitness measure on adaptive belief system is investigated. For comparison, we study pricing dynamics of a financial market populated with chartists perceive losses and gains symmetrically. One of our contributions is validating the agent-based models using real financial data of the Egyptian Stock Exchange. We find that our framework can explain important stylized facts in financial time series, such as random walk price behaviour, bubbles and crashes, fat-tailed return distributions, power-law tails in the distribution of returns, excess volatility, volatility clustering, the absence of autocorrelation in raw returns, and the power-law autocorrelations in absolute returns. In addition to this, we find that loss aversion improves market quality and market stability.

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.

Asset Price Fluctuation and Monetary Policy

Macroeconomic effects of fiscal adjustment: A tale of two approaches

We investigate the short-term effects of fiscal adjustment on economic activity in 20 OECD countries from 1970 to 2009. We compare two approaches: the traditional approach based on changes in cyclically adjusted primary balance (CAPB) and the narrative approach based on historical records. Proponents of the latter argue that it captures discretionary fiscal adjustment more accurately than the traditional approach. We propose a new definition of CAPB that takes account of fluctuations in asset prices and reflects idiosyncratic features of fiscal policy in individual countries. Using this new definition, we find that fiscal adjustments always have contractionary effects on economic activity in the short term; we find no evidence of expansionary (non-Keynesian) fiscal adjustments. Spending-based fiscal adjustments lead to smaller output losses than tax-based fiscal adjustment. These results are in line with the literature using the narrative approach, suggesting that the CAPB, when correctly specified, can be used as a measure of fiscal adjustments.

Sentiments, Financial Markets, and Macroeconomic Fluctuations

This paper studies how financial information frictions can generate sentiment-driven fluctuations in asset prices and self-fulfilling business cycles. In our model economy, exuberant financial market sentiments of high output and high demand for capital increase the price of capital, which signals strong fundamentals of the economy to the real side and consequently leads to an actual boom in real output and employment. In a two-country setting, our sentiment-driven fluctuations help explain global recessions and the cross-country comovement puzzles. In the extension to the dynamic OLG setting, our model demonstrates that sentiment shocks can generate persistent fluctuations in output and employment, holding the promise to explain persistent business cycle fluctuations.

Empirical research on monetary policy, asset prices and inflation: an analysis based on provincial panel data in China

In this article, we investigate the dynamic correlations among monetary policy, asset prices and inflation and assess the regional effects of monetary policy in China for the period October 2007 to July 2013. We focus on the interdependencies among monetary policy and asset price fluctuations by using the Shanghai Interbank Offered Rate as the preferred variable for analysing monetary policy movement. In particular, we apply a vector autoregressive model in a panel setting, which allows researchers to examine variations over time or across individual regions. The empirical results presented herein indicate that monetary policy reacts actively to asset prices, although it is still shown to be ineffective. In addition, we find that asset prices display some regional differences in their response to an unexpected monetary policy shock.

Understanding Uncertainty Shocks and the Role of Black Swans

Economic uncertainty is a powerful force in the modern economy. Recent work shows that surges in uncertainty can trigger business cycles, bank runs and asset price fluctuations. But where do sudden surges in uncertainty come from? This paper provides a data-disciplined theory of belief formation that explains large fluctuations in uncertainty. It argues that people do not know the true distribution of macroeconomic outcomes. Like Bayesian econometricians, they estimate a distribution. Our main contribution is to explain why real-time estimation of distributions with non-normal tails are prone to large uncertainty fluctuations. We use theory and data to show how small changes in estimated skewness whip around probabilities of unobserved tail events (black swans). Our estimates, based on real-time GDP data, reveal that revisions in the estimates of black swan risk explain most of the fluctuations in uncertainty.

The Role of Economic, Fiscal, and Financial Shocks in the Evolution of Public Sector Pension Funding

Many studies have documented the pervasive underfunding of public sector pension plans in the United States in recent years. The deterioration of the funded status of public pension plans coincided with severe fiscal crises that state and local governments experienced in the 2000s. This development has led to a suspicion that state and local governments have decreased employer pension contributions as a backdoor means of running fiscal deficits. In this paper, the authors investigate the extent to which this phenomenon has occurred. They estimate panel data regressions using the Boston College Center for Retirement Research’s Public Plans Database, which provides data for 2001 through 2010. The authors find that contrary to popular belief, plan sponsors do not reduce their contributions in response to negative fiscal or economic shocks. In contrast, plan sponsors’ contributions to their pension plans increase in response to growth in their unfunded liabilities. The authors document that the public pension underfunding crisis during the 2000s developed largely as a consequence of portfolio returns that fell short of expectations. Public pension plans’ assets portfolios have a relatively high share of equities and other risky assets, leaving the plans’ funded status vulnerable to asset price fluctuations. Although plan sponsors increased their contributions in response to the growth of unfunded liabilities, they did not do so by enough to fully counteract the effect of the subpar portfolio returns. This finding holds across the spectrum of plans ranked in terms of funded status in 2010.

What Asset Prices Should Be Targeted by a Central Bank?

This paper investigates the monetary policy design for restoring equilibrium determinacy. Our interests are whether a central bank should respond to asset price fluctuations, and if so, what asset prices should be targeted. We show that a monetary policy response to the price of a productive tangible asset (capital price) is helpful for equilibrium determinacy, while that to the price of an intangible asset that reflects a firm's profit (share prices) is a source of equilibrium indeterminacy. This result comes from the two assets' prices moving in opposite directions in response to a permanent increase in inflation.

The role of financial intermediaries in monetary policy transmission

The recent financial crisis has stimulated theoretical and empirical research on the propagation mechanisms underlying business cycles, in particular on the role of financial frictions. Many issues concerning the interactions between banking and monetary policy forced policy makers to redefine economic policies, and motivated macroeconomists to focus on the implications of financial intermediation constraints for asset price fluctuations, the behavior of non-financial firms, households, governments and in turn for real macroeconomic performance. This paper surveys research on the role of financial intermediaries and financial frictions in the transmission of monetary policy and discusses how to design both the new banking regulatory and supervisory structures and monetary policy in order to stabilize the economy. It also serves as an introduction to this special issue.

Generalised diffusion model of asset price fluctuations

We present a (semi-) analytical model of asset fluctuations using the framework of Fokker-Planck equations, together with generalised diffusion coefficients. Allowing for time dependence of the coefficients D 1 and D 2 provides a route to the characterization of the long- and short-time nature of autocorrelation functions, as is demonstrated for Dow Jones 1993–2012 financial data.

Asset Prices, Nominal Rigidities, and Monetary Policy: Negative Monetary Policy Responses to Asset Price Fluctuations

Carlstrom and Fuerst [“Asset Prices, Nominal Rigidities, and Monetary Policy,” Review of Economic Dynamics, Vol. 10, 2007, pp. 256-275] find that a positive monetary policy response to share prices is a source of equilibrium indeterminacy. In this note, we investigate the negative response of a central bank to share prices. We find that a negative monetary policy response to share prices is also a source of equilibrium indeterminacy.

Banking Competition, Collateral Constraints, and Optimal Monetary Policy

We analyze optimal monetary policy in a model with two distinct financial frictions: monopolistically competitive banks that charge endogenous lending spreads, and collateral constraints. We show that welfare maximization is equivalent to stabilization of four goals: inflation, output gap, the “consumption gap” between borrowers and savers, and a “housing gap” that measures the distortion in the distribution of the collateralizable asset between both groups. Collateral constraints create a trade‐off between stabilization goals. Following both productivity and financial shocks, and relative to strict inflation targeting, the optimal policy implies sharper movements in the policy rate, aimed primarily at reducing fluctuations in asset prices and hence in borrowers' net worth. The policy trade‐offs become amplified as banking competition increases, due to the fall in lending spreads and the resulting increase in borrowers' leverage.

Market Turmoil and Destabilizing Speculation

This paper explores how speculators can destabilize financial markets by amplifying negative shocks. During periods of turmoil created by an uncertainty shock, speculators react to declining asset prices by liquidating their holdings in hopes of buying them back later at a gain, despite the asset's cash flows remaining the same throughout and the absence of financial constraints. A reduction in search frictions tends to exacerbate fluctuations in asset prices. At the root of these results are the strategic complementarities between speculators expected to follow similar strategies in the future. The model sheds new lights on recent financial events and provides testable empirical implications.

The Impact of House Prices on Consumer Credit: Evidence from an Internet Bank

This paper shows that house price fluctuations can have a significant impact on credit availability. Data from Prosper.com, a peer‐to‐peer lending site that matches borrowers and lenders to provide unsecured consumer loans, indicate that homeowners in states with declining house prices experience higher interest rates, greater credit rationing, and faster delinquency. We find especially large effects for subprime borrowers whose balance sheets are likely most exposed to asset price declines. This evidence suggests that asset price fluctuations can play an important role in determining credit conditions and are thus a potentially significant mechanism for propagating macroeconomic shocks.
