Procyclicality of the comovement between dividend growth and consumption growth

Duffee (2005) shows that the amount of consumption risk (i.e., the conditional covariance between market returns and consumption growth) is procyclical. In light of this “Duffee Puzzle,” I empirically demonstrate that the conditional covariance between dividend growth (i.e., the immediate cash flow part of market returns) and consumption growth is (1) procyclical and (2) a consistent source of procyclicality in the puzzle. Moreover, I solve an external habit formation model that incorporates realistic joint dynamics of dividend growth and consumption growth. The procyclical dividend-consumption comovement entails two new procyclical terms in the amount of consumption risk via cash flow and valuation channels, respectively. These two procyclical terms play an important role in generating a realistic magnitude of consumption risk. In contrast to extant habit formation models, the conditional equity premium no longer increases monotonically when a negative consumption shock arrives because it might lower the amount of risk while increasing the price of risk.     

Aggregate implications of indivisible labor, incomplete markets, and labor market frictions

We study the impact of tax and transfer programs on steady-state allocations in a model with search frictions, an operative labor supply margin, and incomplete markets. In a benchmark model that has indivisible labor and incomplete markets but no trading frictions we show that the aggregate effects of taxes are identical to those in the economy with employment lotteries, though individual employment and asset dynamics can be different. The effect of frictions on the response of aggregate hours to a permanent tax change is highly nonlinear. There is considerable scope for substitution between “voluntary” and “frictional” nonemployment in some situations.     

An equilibrium approach to financial stability analysis: the Colombian case

This paper studies in detail the performance of a general equilibrium model of the financial system when applied to the case of Colombia. This model was designed following closely the work by Goodhart et al. (Ann Fin 2, 1–21, 2006b). The results suggest that the model performs satisfactorily, especially in the prediction of short-run trends (2 years). A shortcoming of the results is a slight overestimation of several trends in the medium to long-term. There is however room to progress, particularly in terms of the incorporation of idiosyncratic features of the Colombian financial system into the model.      

Macroeconomic dynamics in a model of goods,labor, and credit market frictions

Goods market frictions drastically change the dynamics of the labor market, both in terms of persistence and volatility. In a model with three imperfect markets – goods, labor, and credit – we find that credit and goods market imperfections are substitutable in raising volatility. Goods market frictions are unique in generating persistence. Two key mechanisms in the goods market generate large hump-shaped responses to productivity shocks: countercyclical goods market tightness and prices alter future profit flows and raise persistence; procyclical search effort of consumers and firms raises amplification. Goods market frictions are thus key in understanding labor market dynamics.     

Comment on: “Inflation dynamics with search frictions: A structural econometric analysis” by Krause, Lopez-Salido and Lubik

The implications of search frictions on the inflation dynamics are shown here for the case with wage adjustments typically belonging to the New Keynesian model, not to the Mortensen–Pissarides framework. In that model variant, I identify the role of search frictions by an additional term entering the slope coefficient of the inflation equation. After a numerical exercise, I find results that are in line with those obtained by Krause et al. [2008. Inflation dynamics with search frictions: a structural econometric analysis. Journal of Monetary Economics 55, doi:10.1016/j.jmoneco.2008.05.003.].

Estimating changes in supervisory standards and their economic effects

The disappointingly slow recovery in the U.S. from the depths of the financial crisis once again focused attention on the relationship between financial frictions and economic growth. Some bankers and borrowers suggested that unnecessarily tight supervisory policies were a constraint on new lending that hindered the recovery. This paper explores one aspect of supervisory policy: whether the standards used to assign commercial bank CAMELS ratings have changed materially over time (1991–2013). Models incorporating time-varying parameters or economy-wide variables suggest that standards used in the assignment of CAMELS ratings over the post-crisis period generally were in line with historical experience. Indeed, each of the models used suggests that the variation in supervisory standards has been relatively small in absolute terms over most of the sample period. However, we show that when this measure of supervisory stringency becomes elevated, it has a noticeable dampening effect on lending activity in subsequent quarters.     

Credit distortion and financial crisis

A simple and consistent theory based on credit distortion is developed to understand the origin of financial crises in the emerging markets. We prove that without the guarantee of various government agencies on the credit risk of foreign loans, the interest rate on foreign loans would be the same as the domestic loans, which would eliminate the incentive to borrow foreign loans on a great scale. We demonstrate that the common phenomena preluding the crisis, such as heavy foreign borrowing and overinvestment in real estate, are rational choices when a particular currency is overvalued and cheap credit is available.

Monetary aggregates and the business cycle

A monetary aggregate consisting predominantly of zero-maturity deposits, called MZM, tends to systematically lead output in the US business cycle. Such fluctuations are observed both before and after the 1979 monetary policy change. Similar dynamics are obtained in a model with multi-stage production and purchase-size heterogeneity when agents optimally choose their mix of cash, checkable, and time deposits used in transactions. The causality in the model runs from real activity to money, rather than the other way around. Although the monetary base is endogenous, through a Taylor-type rule, the lead in MZM is primarily driven by deposit creation.     

An analysis of euro area sovereign CDS and their relation with government bonds

We compare the market pricing of euro area government bonds and the corresponding Credit Default Swaps (CDSs). In particular, we analyse the “basis” defined as the difference between the premium on the CDS and the credit spread on the underlying bond. Our sample of weekly data covers the period from January 2007 to December 2012 and contains several episodes of sovereign market distress. Overall, we observe a complex relationship between the derivatives market and the underlying cash market characterised by sizable deviations from the no-arbitrage relationship (i.e. basis equal to zero). We show that short-selling frictions explain the persistence of positive basis deviations while funding frictions explain the persistence of negative basis deviations which are observed for countries with weak public finances. Moreover, we show that the “flight-to-quality/liquidity” phenomenon in bond markets is a key driver of the large positive basis of better rated countries.

Credit risk transfer and financial sector stability

In this paper, we study credit risk transfer (CRT) in an economy with endogenous financing (by both banks and non-bank institutions). Our analysis suggests that the incentive of banks to transfer credit risk is aligned with the regulatory objective of improving stability, and so the recent development of credit derivative instruments is to be welcomed. Moreover, we find the transfer of credit risk from banks to non-banks to be more beneficial than CRT within the banking sector. Intuitively, this is because it allows for the shedding of aggregate risk which must otherwise remain within the relatively more fragile banking sector. Therefore, regulators should act to maximize the benefits from CRT by encouraging the development of instruments favorable to the cross-sectoral transfer of aggregate credit risk (including basket credit derivatives such as collateralized debt obligations). Finally, we derive the optimal regulatory stance for banks relative to non-bank financial institutions. We show that a level playing field approach is sub-optimal. Regulatory stances should be set to actively encourage cross-sector CRT, first because of the higher fragility of the banking sector and second to induce banks to incur the costs of CRT which otherwise lead them to undertake an insufficient amount of CRT.

Finance and consumption volatility: Evidence from India

The main objective of this paper is to explore the determinants of private consumption growth volatility in India, focusing on the role of financial sector policies. Using data for India over the period 1950-2005, the results show that the implementation of financial repressionist policies is strongly associated with lower consumption volatility. The results remain robust after controlling for a wide range of macroeconomic shocks and variables. The presence of a threshold effect implies that the benefits of financial reforms in reducing consumption volatility can only be reaped when the financial system becomes sufficiently liberalized. The results also indicate that the presence of a more open financial system may serve to dampen fluctuations in private consumption.
