The second essay shows that when estimating time-series regressions of unknown functional form, multicollinearity can make regressions very sensitive to small misspecifications of nonlinear relationships. This essay shows that a simple seminonparametric estimator can help to solve this problem. Specifically, adding a flexible time trend to the regression model will give significantly less biased OLS estimators, even if the model remains misspecified. This is because the trend is now fitted directly, so the other explanatory variables need to fit only fluctuations around the trend. A consistency result is proven, and Monte Carlo experiments are used to illustrate the approach.

I show how these effects can be distinguished from each other empirically. I use individual-level Nielsen data to analyze the effects of tune-in ads for television shows. I find that the consideration set effect of advertising is significant and large in my data, while other effects of advertising are minor, with important implications for firms' advertising strategies. In the third essay (joint with Bharat Anand), we focus on systematic heterogeneity in firms' valuations. We decompose overall variation in firms' excess values into diversification discount, systematic heterogeneity (firm random effects) and temporary shocks. We find that the magnitude of systematic heterogeneity is large in absolute terms, and large relative to the mean diversification discount. This highlights the importance of understanding the fundamental drivers of such systematic differences in performance, and suggests that the value consequences of diversification (which have attracted a lot of attention in the literature) are relatively minor compared to other systematic determinants of firm value.

This dissertation consists of one essay in financial econometrics and two essays in quantitative industrial organization. The first essay studies the relationship between stock return volatility and current and prior shocks to oil price volatility. We study the behavior of aggregate stock markets as well as individual industry sectors. Our results show that lagged stock return volatility is the main determinant of current stock return volatility in aggregate markets, with oil price volatility providing no additional information that can be used to forecast stock return volatility. For individual industry sectors, we find a robust and stable prediction relationship only for the chemicals industry. Additional estimation exercises confirm the robustness of these results. The second essay uses a Bertrand-Nash price-competition framework to models a vertically integrated provider (VIP) that is a monopoly supplier of an essential input for downstream production. An input price that is "too high" can lead to inefficient foreclosure and one that is "too low" creates incentives for nonprice discrimination. The range of non-exclusionary input prices is circumscribed by the input prices generated on the basis of upper-bound and lower-bound displacement ratios. The admissible range of the ratio of downstream to upstream "price-cost" margins for the VIP is increasing in the degree of product differentiation and reduces to a single ratio in the limit as the products become perfectly homogeneous. The third essay explores the relationship between upstream input prices and downstream market exclusion under a Stackelberg quantity-competition framework. Market exclusion is a concern when input prices are "too high" and "too low" because it can result in inefficient foreclosure and sabotage, respectively. Consistent with the results obtained in the second essay, the safe harbor range of downstream to upstream "price-cost" margin ratios is decreasing in the degree of product homogeneity and approaches a single ratio in the limit as the products become perfectly homogeneous. This single margin ratio preserves equality between the VIP's wholesale and retail "price-cost" margins. A key finding for competition policy is that the bounds of non-exclusionary input prices are markedly wider under Bertrand-Nash competition than they are under Stackelberg competition. Hence, it is critical that the antitrust and regulatory authorities understand the nature of the industry competition so that rules governing permissible conduct are properly calibrated to yield efficient outcomes.

In my dissertation I study econometric methods of causal inference with a particular focus on the use of prediction methods developed by researchers in the fields of statistical learning, machine learning, and pattern recognition. I'm also interested in the application of these methods as well as the more traditional ones to answer relevant policy questions. Chapter 1 (joint with Guido Imbens) considers the synthetic control method developed by Abadie, Diamond, Gardeazabal, and Hainmueller in several influential papers. The method is designed for estimating the effect of a treatment, in the presence of a single treated unit and a number of control units, with pre-treatment outcomes observed for all units. The method constructs a set of weights such that selected covariates and pre-treatment outcomes of the treated unit are approximately matched by a weighted average of the control units (the synthetic control). The weights are restricted to be nonnegative and sum to one. These restrictions are important partly because they make it easier for the procedure to obtain unique weights even when the number of lagged outcomes is modest relative to the number of control units, a common setting in applications. In the chapter we propose a generalization of the synthetic control procedure that allows the weights to be negative, and their sum to differ from one, and that allows for a permanent additive difference between the treated unit and the controls, similar to the difference-in-difference procedures. The weights directly minimize the distance between the lagged outcomes for the treated and the control units, using elastic net regularization to deal with a potentially large number of possible control units. In Chapter 2 (joint with Ali Yurukoglu) we quantify how bargaining power derived from firm size affects the analysis of downstream mergers and the profitability of downstream entry in the multichannel television industry. We estimate an empirical model of the industry which features negotiations between the upstream content producers and the downstream distributors of varying size. We estimate that large distributors like Comcast are able to negotiate about 25% lower content fees than smaller downstream firms such as Cablevision. We evaluate the short-run welfare effects of several recently reviewed mergers taking into account the size effects in negotiations. We also assess the degree to which size based bargaining power creates contracts which are a barrier to entry for new distributors.

Lawrence Klein, University of Pennsylvania Jaime Marquez, Federal Reserve BoarrI* All examination of the economics literature over the last twenty years reveals a marked tendency towards polarisation. On the one hand, there has been a propensity to develop theoretical models which have little connection with either empirical verification or problems requiring immediate attention. On the other iland, empirical analyses are generally typified by testing for its own sake, with limited examination of the implications of the results. As a result, the number of papers confronting theory with facts towards the solution of economic problems has been on the decline for years. To fill this growing gap in the literature, we have invited a number of authors to write papers using both theoretical and empirical techniques to address current issues of interest to the profession at large: the US trade deficit and the global implications of policies that attempt to reduce it, the international ramifications of the debt crisis, the international oil market and its implications for the US oil industry, and the development of new econometric techniques. In addressing these issues, each author has approached the subject matter from an eclectic standpoint - that is, avoiding strict adherence to a given doctrine.
