PhD

Parag Waknis defends, heads to UMass-Dartmouth

On Friday, September 9, 2011, Parag Waknis defended his dissertation titled “Essays on Economics of Leviathan Monetary and Fiscal Policies” under the supervision of Professor Christian Zimmermann.

Here is a short description of his dissertation: 

Time and again situations arise in various countries where fiscal policy drives the monetary policy. This might happen as a result of unusual situations like the current financial crisis or because of lack of sufficient tax revenues. There is not much literature modeling such policy environment using a money search framework. This dissertation aims to bridge this gap by modifying a much often-used money search model to include a Leviathan or a utility maximizing central bank. The first essay studies the nature of optimal monetary policy of this monetary authority. The analysis suggests multiple outcomes with actual realization depending on context specific factors. For example, fiscal profligacy is associated with higher inflation- a fact borne out by many actual examples. The second essay evaluates a thought exercise in institutional design to control inflation in such a context. It extends the model in the first essay to create an environment with currency competition and then shows that doing so leads to a better inflation outcome under reputation concerns. The third essay looks at the political economy of fiscal policy. To account for a typical developing country setting a model with differentiated political platforms and credit-constrained voters is laid out.  The credit-constrained voters depend on local public goods provision for smoothing consumption in the presence of shocks. The model’s implications are then tested with data on 17 Indian states for the period of 20 years. The data does lend substantive support to the contention that political cohesiveness affects the nature of spending. Put together, the three essays form a body of theoretical and empirical research shedding light on a monetary policy environment that features close connection with the fiscal policy.

Parag started his tenure track position on September 1, 2011, and relocated from New York City to New Bedford, MA.  Congratulations, Parag!

Nicoleta Iliescu defends, heads to IONA College

In August 2011, Nicoleta Iliescu defended her dissertation entitled “Three Essays on Antidumping,” under the supervision of Professor Xenia Matschke. The unifying theme of the dissertation is the antidumping, currently the most intensively-used temporary trade instrument worldwide.  In the first chapter of the dissertation, Nicoleta investigates the impact of the political lobbying on the antidumping practices in the US. This is an empirical paper in which a newly-constructed lobbying dataset is used.  In the second chapter, in a theoretical model, Nicoleta explores the link between the existing national antidumping laws and the amount of the R&D undertaken by industries that can use antidumping as a protectionist tool. The third chapter analyzes the welfare effects of the Byrd Amendment, a law passed in the US in 2001, which had profound implications on how the collected antidumping duties were distributed.

Starting Fall 2011, Nicoleta is a Visiting Assistant Professor of Economics at Iona College in New York.

Paramita Dhar defends, heads to CCSU

On 17th June, 2011, Paramita Dhar defended her dissertation entitled “Essays on the Economics of Housing” under the supervision of Prof. Stephen L. Ross.  Paramita’s dissertation examined two different questions about housing and location choice. In her first essay, she analyzed the impact of school quality on property values using a differences-in-differences strategy. In the other two essays of her dissertation, she focused on the issue of discrimination against minority homebuyers that might lead to the segregation of neighborhoods. In both of these essays she used fair housing audit data from the 2000 Housing Discrimination Study on three large minority groups in Los Angeles to examine the causes of spatial variation of the nature of discrimination.

This fall, Paramita will be heading to Central Connecticut State University as a tenure-track Assistant Professor of Economics.

Catalina Granda-Carvajal defends, heads to Universidad de Antioquia

On June 21, 2011, Catalina Granda-Carvajal defended her dissertation, “Essays on the Macroeconomic Effects of the Unofficial Sector.”  Under the valuable supervision and support of her advisor, Prof. Christian Zimmermann, Catalina’s thesis focuses on how the unofficial sector and its intrinsic characteristics are related to aggregate fluctuations.  At an empirical level, she determines how business cycle stylized facts vary across countries with the extent of the shadow economy and compares the resulting patterns with predictions from existing models featuring underground activities.  Also, she incorporates an irregular sector into a real business cycle model to challenge the notion that fluctuations in the official and unofficial sectors are negatively correlated.  Using a similar theoretical framework, she finally addresses how informal firms’ limited access to credit affects macroeconomic and firm volatility.

Pieces of Catalina’s dissertation have been presented in a couple of international conferences and a section was selected for publication at the International Economic Journal last December.  In addition to her thesis, she has taken part in an interdisciplinary project on options for brownfields revitalization in Connecticut under the supervision of Prof. Kathleen Segerson.  She currently holds a tenure-track position at Universidad de Antioquia in Medellín (Colombia).

Xiaoming Li defends dissertation and heads to Freddie Mac

Xiaoming Li defended his PhD dissertation under the supervision of Prof. Ross on Monday, April 25, 2011.

Theoretical models and empirical analyses argue that mortgage underwriting is a dynamic process in which previous mortgage and housing market conditions affect current mortgage approvals. Neighborhoods likely differ in important ways and over important events or shocks that influence both housing prices and mortgage underwriting decisions. This potential endogeneity complicates the causal analyses and failure to control for neighborhood heterogeneity risks confounding spurious and true state dependence. Xiaoming’s dissertation attempts to examine the housing dynamics and distinguish between sources of time persistence on neighborhood mortgage underwriting. Specifically, Xiaoming extends traditional and recently developed dynamic panel data techniques for use of repeated, clustered cross-sectional individual mortgage applications linearly and nonlinearly, respectively.

Xiaoming now heads to Freddie Mac as a Credit & Prepayment Modeling, Senior. We wish him the best of luck!

Alumna Yanna Wu reports on life after UConn

Fed Chairman Ben Bernanke could unfortunately not make it to the “Life after UConn” event organized by the Association of Graduate Students in Economics last Friday. Instead, Yanna Wu spoke.

Dr. Wu graduated with a Ph.D. in economics from UConn in 2004, under the supervision of Prof. Ray. Right after that, she joined PricewaterhouseCoopers LLP. in their New York office. She currently is a manager in the transfer-pricing group, which is a part of the tax practice, providing tax and economic consulting services for multinational enterprises on their inter-company pricing arrangements. Transfer pricing is a multidisciplinary field that encompasses accounting, tax, economics, finance, and law. Her main responsibilities include project solicitation and management.

Dr. Wu covered the following topics: (i) the current job market for new Ph.D. graduates in economics; (ii) potential job opportunities; (iii) differences between working in academia and in industry; (iv) how graduate students can prepare for the job market; and (v) her experience. After the lecture, Dr. Wu answered questions from graduate students.

New slate of PhD students going on the job market

Tao Chen: (Advisor: Tripathi)
My research on econometrics is both theoretical and applied. The theoretical part focuses mainly on microeconometrics and functional data analysis. The applied work is within the fields of labor and urban economics.

Paramita Dhar (Advisor: Ross)
My dissertation examines two different questions about housing and location choice. In the first essay, I apply a difference-in-difference model to capture the causal effect of school quality on house prices by looking at houses located on school district boundaries in Connecticut. The rest of the dissertation deals with detailed spatial analysis of the nature of housing discrimination in the context of multiple minority groups in Los-Angeles using Housing Discrimination Study (2000).

Leshui He (Advisor: Langlois)
My dissertation departs from the standard property rights theory of the firm of Grossman, Hart and Moore and develops the interaction between the ownership of the firm and the ownership of the alienable assets. By defining the ownership of the firm following Alchian and Demsetz (1972), I create a theoretical framework allowing for independent allocations of the two ownership rights. Then I move on and utilize the multi-tasking agent model under this framework to run a level horse race among four alternative organizational forms. The model sheds lights on conditions under which human-capital owned firms can be optimal, and offers tentative explanations to the fact that firms usually collectively own alienable assets.

Nicoleta Iliescu (Advisor: Matschke)
In my job market paper (“US Lobby Activity and Antidumping Outcomes”), I investigate the impact of lobbying on the antidumping practices in the US. Currently, antidumping is the most heavily used temporary tariff measure both worldwide and in the US. Thus, it becomes an appropriate avenue of studying how political pressure shapes the level of protection some domestic industries receive. The empirical results I derive in the paper reinforce the hypothesis that the political clout plays an important role in granting trade protection through antidumping duties.

Nick Jolly (Advisor: Couch)
My dissertation focuses on the consequences of job displacement.  The first paper from my dissertation, which was published in Research on Aging, shows that displaced workers experience larger earnings losses if they are older at the time of job loss.  The second paper examines how earnings losses vary over different phases of the business cycle; the final paper examines how this type of involuntary job loss influences the inter-temporal movement of workers throughout the earnings and income distributions.

Steve Kuchta (Advisor: Miceli)
My dissertation examines the role patent term restoration plays in incentivizing pharmaceutical development and clinical trials behavior. The unique position of pharmaceuticals, who must spend portions of their patent term achieving regulatory approval, forces the effective patent life to balance more interests relative to the standard patenting story. A law and economics approach is utilized to expose the competing dynamics and thereby to provide theoretical foundations for the 1984 Hatch-Waxman Act. The modeling also informs current policy discussion regarding adding exclusivity protection to patent protection in the emergent biopharmaceutical industry.

Xiaoming Li (Advisor: Ross)
My dissertation examines the dynamics in the housing and mortgage markets. Specifically I attempt to identify the “true state dependence” from the “spurious state dependence”. In the first essay, I specify a linear probability model to test the neighborhood information externalities in mortgage underwriting. In the second essay, I propose an analytically bias-corrected fixed effects estimator that is robust to the incidental parameters bias for panel fractional response models. In the third essay, I apply the proposed bias-corrected estimator to empirically examine the impact of local housing markets on neighborhood mortgage underwriting.

Shalini Mitra (Advisor: Zimmermann)
My dissertation examines the channels through which volatility of key variables like output, employment, investment and consumption is affected – both at the firm and the aggregate level and their implications. I specifically consider degree of financial development of a nation, research and development expenditure of firms, and the presence of an informal sector.

Zinnia Mukherjee (Advisor: Segerson)
My research is in applied microeconomics. My dissertation essays deal with the design and evaluation of conservation policies, with a specific focus on protection of endangered species. In particular, the three essays analyze (i) the effectiveness of voluntary approaches and the role of background regulatory threat in mitigating stochastic bycatch, (ii) the welfare effects of unilateral bycatch policies in an open economy, and, (iii) the economic impact of the TED regulation (a major U.S. bycatch regulation) on the U.S. shrimp industry. Post dissertation, my research projects include (i) studying the spatial and temporal effects of marine hypoxia on Long Island Sound harvest and fishers’ behavioral responses to the phenomenon, (ii) analyzing the effect of political ideology on state level income inequality for U.S. states, and, (iii) examining the role of U.S. state laws on sexual crime and crime location choice of repeat offenders.

Michael Stone (Advisor: Miceli)
I present a theory which extends the traditional economic model of punitive damages by incorporating litigation costs. Incorporating litigation costs into the model provides a possible justification for punitive damage caps. At the optimum, caps balance deterrence against the cost of litigation. Empirical testing of the model is performed via Cox proportional and parametric hazard analyses, using a panel dataset from 1981 to 2007. The empirical results reveal a positive relationship between judicial and legal expenditures (a proxy for legal costs) and cap enactment, and a negative relationship between state GSP (a proxy for damages) and cap enactment. Cap enactment is also influenced by political ideology.

Parag Waknis (Advisor: Zimmermann)
In my dissertation, I explore the nature of optimal monetary policy under a Leviathan monetary authority. Such a monetary authority is a reality wherever governments rely heavily on seigniorage. In a model based on Lagos and Wright (2005), I characterize a Markov perfect equilibrium as well as equilibrium under reputational concerns for such monetary authority. While, there are multiple equilibriums in general, under certain conditions we can narrow down the set of equilibriums to one and show that it is characterized by higher inflation. I then add one more Leviathan central bank to the model to see if adding a competitive element implies a lower rate of inflation in equilibrium. I plan to use the insights from these models to analyze sub-national spending in developing countries like India. Understanding the policies of such central banks or governments is critical given today’s interdependent global policy environment.

Juan-Pedro Garces defends his dissertation and heads South

Juan-Pedro Garces defended on 4 August 2010 his dissertation under the supervision of Prof. Susan Randolph. The main topic of his dissertation is how education contributes to economic development. In one of the chapters, he pays special attention to the quality of education, trying to determine whether private schools deliver more educational quality than public ones, with special reference to the case of Chile, his native country. The dissertation also tackles the issue of the influence of population density on productivity, and how is affected by the level of education of the population. For this purpose, the study uses panel data on a sample of more than 100 countries, mostly developing ones. The third chapter of the dissertation focuses on institutions, testing the mainstream literature on the effects of institutional governance on economic growth and development. His work tries to determine the way in which the level of education affects institutional governance, finding a new channel through which education can enhance economic growth.

Juan-Pedro will be a visiting instructor at Wake Forest University, North Carolina.
