21. Debt Servicing, Aggregate Consumption, and Growth

Abstract:
We develop a neo-Kaleckian growth model that emphasizes the importance of consumption behavior. In our model, workers first make consumption decisions based on their gross income, and then treat debt servicing commitments as a substitute for saving. Workers’ borrowing is induced by their desire to keep up with the consumption standard set by rentiers’ consumption, reflecting an aspect of the relative income hypothesis. As a result of this consumption and debt servicing behavior, consumer debt accumulation and income distribution have effects on aggregate demand, profitability, and economic growth that differ from those found in existing models. We also investigate the financial sustainability of the Golden Age and Neoliberal growth regimes within our framework. It is shown that distributional changes between the Golden Age and the Neoliberal regimes, together with corresponding changes in consumption emulation behavior via expenditure cascades, suffice to make the Neoliberal growth regime unsustainable.

22. Working Paper Exploring the Concept of Homeostasis and Considering its Implications for Economics

Abstract:
The reality of human homeostasis expands the views on preferences and rational choice that are part of traditionally conceived Homo economicus and casts doubts on economic models that depend only on an “invisible hand” mechanism. In its standard format, the concept of homeostasis refers to the ability, present in all living organisms, of continuously maintaining certain functional variables within a range of values compatible with survival. The mechanisms of homeostasis were originally conceived as strictly automatic and as pertaining only to the state of an organism’s internal environment. In keeping with this concept, homeostasis was, and still is, often explained by analogy to a thermostat: upon reaching a previously set temperature, the device commands itself to either suspend the ongoing operation (cooling or heating), or to initiate it, as appropriate. This traditional explanation fails to capture the richness of the concept and the range of circumstances in which it can be applied to living systems. Our goal here is to consider a more comprehensive view of homeostasis. This includes its application to systems in which the presence of conscious and deliberative minds, individually and in social groups, permits the creation of supplementary regulatory mechanisms aimed at achieving balanced and thus survivable life states but more prone to failure than the fully automated mechanisms. We suggest that an economy is an example of one such regulatory mechanism, and that facts regarding human homeostasis may be of value in the study of economic problems. Importantly, the reality of human homeostasis expands the views on preferences and rational choice that are part of traditionally conceived Homo economicus and casts doubts on economic models that depend only on an “invisible hand” mechanism.

23. Risk, Financial Development and Firm Dynamics

Abstract:
I document that the average productivity of firms tends to increase, and its variance to decrease, as they age. These two facts combined suggest that managers learn to reduce their mistakes as they operate. I develop a quantitative framework mimicking these dynamics and find that young firms have substantially higher financing costs due to lower and riskier returns. In this scenario, a reduction in the financial development of an economy raises disproportionately the cost of credit of young-productive firms increasing the input misallocation within this subgroup. To test the validity of the theory, I find that the data confirms some novel predictions on a series of firm-level moments. Finally, I show that introducing these two facts allows the model to better explain the relation between financial and economic development.

24. Understanding the Great Recession

Abstract:
We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in the wages and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small size of the drop in inflation that occurred during the Great Recession.

25. Generating Options-Implied Probability Densities to Understand Oil Market Events

Abstract:
We investigate the informational content of options-implied probability density functions (PDFs) for the future price of oil. Using a semiparametric variant of the methodology in Breeden and Litzenberger (1978), we investigate the fit and smoothness of distributions derived from alternative PDF estimation methods, and develop a set of robust summary statistics. Using PDFs estimated around episodes of high geopolitical tensions, oil supply disruptions, and macroeconomic data releases, we explore the extent to which oil price movements are expected or unexpected, and whether agents believe these movements to be persistent or temporary.

26. Inextricability of Autonomy and Confluence in Econometrics

Author:
Duo Qin
Publication Date:

Content Type:
Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
This paper examines how ‘confluence’ and ‘autonomy’, two key concepts introduced by Frisch around 1930, have disappeared in econometrics textbooks and why only some fragments of the two have survived mainstream econometrics. It relates the disappearance to the defect in the textbook position of equating a priori theoretical models as correct structural models unequivocally. It shows how the confluence-autonomy pair in unity reflects the complexity of econometricians’ goal to find and verify robust and economically meaningful models out of numerous interdependent variables observable from the real and open world. The complexity deems it essential for applied research to have a set of model design rules combining both a priori substantive reasoning and a posteriori statistical testing. Such a need also puts the task of ensuring an adequately minimum model closure to top priority for applied modellers, a task much more important than the textbook task of parameter estimation.

27. Modelling Scale Effect in Crosssection Data:The Case of Hedonic Price Regression

Author:

Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
An innovative and simple experiment with cross-section data ordering is carried out to exploit a basic and common feature between many economic variables – nonlinear scale dependence. The experiment is tried on hedonic price regression models using two data sets, one for automobiles and the other computers. The key findings are: (a) Hedonic price indices can be significantly biased if they are constructed using models which disregard possible nonlinear scale effects latent in random data samples; (b) Scale-based data ordering offers considerable potential to filter such scale-dependent information from cross-section samples; (c) The filtering can be easily carried out by systematic adoption of dynamic modelling methods.

28. A Robust Neighborhood Truncation Approach to Estimation of Integrated Quarticity

Abstract:
We provide a first in-depth look at robust estimation of integrated quarticity (IQ) based on high frequency data. IQ is the key ingredient enabling inference about volatility and the presence of jumps in financial time series and is thus of considerable interest in applications. We document the significant empirical challenges for IQ estimation posed by commonly encountered data imperfections and set forth three complementary approaches for improving IQ based inference. First, we show that many common deviations from the jump diffusive null can be dealt with by a novel filtering scheme that generalizes truncation of individual returns to truncation of arbitrary functionals on return blocks. Second, we propose a new family of efficient robust neighborhood truncation (RNT) estimators for integrated power variation based on order statistics of a set of unbiased local power variation estimators on a block of returns. Third, we find that ratio-based inference, originally proposed in this context by Barndorff-Nielsen and Shephard (2002), has desirable robustness properties in the face of regularly occurring data imperfections and thus is well suited for empirical applications. We confirm that the proposed filtering scheme and the RNT estimators perform well in our extensive simulation designs and in an application to the individual Dow Jones 30 stocks.

Abstract:
"A three-factor model using the standardized-unexpected-earnings and cashflow-to-price factors explains 15 well-known asset pricing anomalies." Our data-mining experiment provides a backdrop against which such claims can be evaluated. We construct three-factor linear pricing models that match return spreads associated with as many as 15 out of 27 commonly used firm characteristics over the 1971-2011 sample. We form target assets by sorting firms into ten portfolios on each of the chosen characteristics and form candidate pricing factors as long-short positions in the extreme decile portfolios. Our analysis exhausts all possible 351 three-factor models, consisting of two characteristic-based factors in addition to the market portfolio. 65% of the examined factor models match a larger fraction of the target return cross-sections than the CAPM or the Fama-French three-factor model. We find that the relative performance of the complete set of three-factor models is highly sensitive to the sample choice and the factor construction methodology. Our results highlight the challenges of evaluating empirical factor models.

30. The Taylor Rule and Interval Forecast For Exchange Rates

Abstract:
This paper attacks the Meese-Rogoff (exchange rate disconnect) puzzle from a different perspective: out-of-sample interval forecasting. Most studies in the literature focus on point forecasts. In this paper, we apply Robust Semi-parametric (RS) interval forecasting to a group of Taylor rule models. Forecast intervals for twelve OECD exchange rates are generated and modified tests of Giacomini and White (2006) are conducted to compare the performance of Taylor rule models and the random walk. Our contribution is twofold. First, we find that in general, Taylor rule models generate tighter forecast intervals than the random walk, given that their intervals cover out-of-sample exchange rate realizations equally well. This result is more pronounced at longer horizons. Our results suggest a connection between exchange rates and economic fundamentals: economic variables contain information useful in forecasting the distributions of exchange rates. The benchmark Taylor rule model is also found to perform better than the monetary and PPP models. Second, the inference framework proposed in this paper for forecast-interval evaluation can be applied in a broader context, such as inflation forecasting, not just to the models and interval forecasting methods used in this paper.
