Nominal inertia and shock persistence in UK business cycles

A structural VAR methodology is used for UK data to identify and map out the effects of innovations in the money supply, employment, output, wages and prices. Moreover, bands of two standard errors are computed for the impulse response functions so that comment may be made on the significance of the dynamic responses of the variables to the simulated shocks. This allows conclusions to be drawn on the persistence of shocks. Results suggest that output variation is largely determined by aggregate demand shocks over the business cycle frequency. Importantly, evidence is also found of rigidities in the form of price inertia and nominal wage stickiness.     

The Effects of Future Capital Investment and R&D Expenditures on Firms' Liquidity

The paper explores factors that lead to accumulation or decumulation of firms' cash reserves. In particular, the paper empirically examines whether additional future fixed capital and R&D investment expenditures induce firms to change their liquidity ratio while considering the role of market imperfections. Implementing a dynamic framework on a panel of US, UK, and German firms, it is found that firms in all three countries make larger adjustments to cash holdings when they plan additional future R&D rather than fixed capital investment expenditures. This behavior is particularly prevalent among financially constrained firms.     

Using Empirical Point Elasticities to Teach Tax Incidence

Using point elasticities rather than using either arc elasticities or slopes of demand and supply curves provides the best method for teaching students about the economic impacts of excise taxes. Not only does a point-elasticity approach simplify theoretical analysis of tax impacts, but it also allows instructors to take advantage of publicly available empirical estimates of demand and supply elasticities to show students how theoretical results can be applied to real-world tax policy issues. To illustrate these advantages, the authors use several available estimates of point elasticities of demand and supply of raw sugar to calculate the economic impacts of a recently proposed penny-per-pound tax on raw cane sugar grown in the Florida Everglades.     

Changes in volatility of credit spread and market efficiency during rapid growth of credit-related securities

This paper investigates the changes in credit spread volatility during 1993–2001. We find that the credit spreads between junk-grade corporate bonds and Treasury bonds were significantly more volatile in the second half of this period when credit-related securities became popular. In contrast, investment-grade bonds exhibited no significant change in volatility. The junk bonds variance ratios changed from being less than one to greater than one. Using the GJR-Garch model, the conditional volatilities of junk bonds increased in the second half of the period and the mean reversion speeds slowed, suggesting a longer time for mean reversion to occur. Our analysis rules out treasury volatility, credit spread level, equity market return, T-bill rate, curvature of the Treasury curve, financial crisis, quantity of defaults and standard deviation of defaults as explanations for the increase in junk bond volatility. In contrast, volatility of equity returns provides a partial explanation of junk bond spread volatility in the later period.     

Dynamic dissolutions and unifications

I reexamine the key results from the literature on the size and number of countries under different political institutions in a simple dynamic model. I find that the canonical static results that democracies lead to too many too‐small countries and that Leviathans lead to too few too‐large countries no longer necessarily hold. The key dynamic element that drives the new results is that public goods are modeled as public capital; this changes the incentives to unify or divide countries. I also show that there are hysteresis effects on the size and number of countries; that is, arbitrary initial configurations of national boundaries may tend to persist because of the initial public capital location decisions they promote.     

The non-productive entrepreneurial process

A large literature explores the importance of entrepreneurship as the catalyst of economic progress. In contrast, this paper argues that entrepreneurs are the driver of economic stagnation. We analyze the non-productive entrepreneurial process and discuss three channels through which non-productive activities have a multiplier effect culminating in economic decline and stagnation. Drawing on examples of non-productive entrepreneurship from both underdeveloped and developed countries, we provide insight into why economic stagnation persists in the former and why economic decline can occur in the latter.     

First-author conditions: evidence from finance journal coauthorship

We study the trend and the author name-ordering rule in finance publication using the publication records of 21 core finance journals during the period from 1990 to 2004. We empirically model the underlying factors that affect the alphabetical ordering rule among multi-authored finance articles. We find that the choice of alphabetical ordering is based on the quality of the article, institutional heterogeneity, team size and cultural factors. The central argument rests upon the need to signal and the importance of signalling within the context of bargaining behaviour among coauthors. The probability of choosing alphabetical name ordering rule is associated with high article quality, higher ranked institutions, smaller research team and the presence of European authors.     

Joining the World Trade Organization: What is the Impact?

Research has called into question the impact of the World Trade Organization (WTO) on trade. This research, however, has been called into question on both modeling grounds for and failing to utilize comprehensive fixed effects. Others have found that when these factors are accounted for, imports rise by significant amounts. This paper seeks to reconcile these findings. I find that the WTO has a larger, though uneven, impact on exports than imports. The results indicate that the WTO frequently causes imports and exports to move in opposite directions negating any increase in overall trade. The regressions with and without fixed country effects generally demonstrate pattern consistency for generalized results that are robust to change. Owing to the finding that imports rise modestly or even fall without country effects while exports rise, the results imply that countries may not be as interested in liberalizing trade as selling to the world.     

Hispanic agencies and profits of distinction: an examination of the advertising industry as a field of cultural production

This project examines the advertising industry as a self-governing space that is guided by its own internal logics, but is nonetheless influenced by social dynamics at play in the larger social space. Using Bourdieu's theory of practice as a theoretical and analytical framework, this study explores the relationship between cultural capital and economic capital. Specifically, I examine the degree to which Hispanic practitioners have leveraged their knowledge of Latina(o) culture and their proficiency in Spanish as profits of distinction within the marketplace. Qualitative interviews conducted with Hispanic ad agents, general market ad agents and clients reveal that the position that Latinas(os) occupy within the social hierarchy has created both opportunities and boundaries for Hispanic agencies. This paper focuses on the practices that allow Hispanic agencies to isolate Latinas(os) from other consumers, distinguishing them institutionally and entitling them to dedicated marketing resources, but I also discuss the limitations to these practices and how such a narrow expression of the Hispanic agency's cultural capital ultimately limits their access to economic capital.     

Commodity Markets and Commodity Mutual Funds

Fundamental economic factors—market demand and supply conditions—provide the most consistent explanation for trends in commodity prices from 2004 to 2011. This paper presents empirical evidence that the rise and fall of commodity prices on a monthly basis can be strongly linked to the value of the U.S. dollar and the world business cycle—in particular, to the strength or weakness in emerging market economies such as China, Brazil, India, and Russia. Despite concerns raised by some policymakers that increased commodity index investment (the financialization of commodities) has driven commodity price movements, numerous academic studies have concluded that index-based investing has not moved prices or exacerbated volatility in commodity markets in recent years. An examination of weekly and monthly net flows into commodity mutual funds reveals that these flows have little or no effect on the overall growth rate of commodity prices. In particular, weekly flows into commodity mutual funds do not lead to future commodity price changes. These results are consistent with academic papers that find little or no impact of commodity index investors on commodity prices in individual markets. The paper concludes by briefly discussing three key factors that illustrate why flows into commodity mutual funds cannot explain commodity price movements.
