Book Description
My dissertation uses theoretical tools and empirical methods to address substantive questions in the intersection of Macroeconomics and Industrial Organization. In particular, my research focuses on understanding the underlying forces that determine efficiency and distortions. In the first chapter, Privatization, Distortions, and Productivity, I ask that to what extent and through what channels privatization has contributed to the rapid growth of GDP and TFP in China's manufacturing sector. Privatization, like many other industrial policies, affects firms' output and productivity through a direct effect on productivity and an indirect effect on resource allocation. Understanding the consequences of privatization on both productivity and allocative efficiency is crucial for policy evaluation and subsequent reforms. To do so, I first develop a method to separately identify productivity and factor misallocations. This links to two distinct literatures. One is the macro literature on misallocation that use wedges or distortions to measure the deviation from firm's optimal scale. The other is the empirical IO literature to estimate production function using input and output, together with firm's optimal choices. I augment the empirical production function estimation framework by introducing wedges between marginal revenues and marginal costs as an additional unobserved variable that distorts the firms output away from their optimal input choices. And I show that how to identify and estimate productivity, distortions and parameters in production function. I then estimate the productivity and distortion effects of privatization. Finally I propose a decomposition method for aggregate productivity growth to explicitly account for the direct effect of privatization. Second, I discussed market frictions, specifically search and informational frictions that prevents efficient allocations in the labor markets. In Understanding Transitions using Directed Search with Mike Peters (UBC) and Steven Xu (HKU), we develop a directed search model to study worker transitions between jobs in the French labor market. In particular, the model we consider allows workers to have incomplete information about each other's' marketable characteristics (types) at the point where they make their search decisions. The theory provides a series of testable predictions about the relationship between the wage a worker receives at the job that he or she leaves, and the wage they get at their next job. The paper then uses data from the French DADS data set to study transitions in a variety of different labor markets in France in 2007, and compares these transitions to what is predicted by the theory. We find that the labor markets for skilled workers and industrial type of workers support more of our model. Third, I explore the return of productivity and distortions in scientific world. In Is Citation Behavior Biased? The Influence of Journal Editors with Bruno Biais (TSE) and Augustin Landier (TSE), we test the null hypothesis that the number of citations provides an unbiased measure of an article's scientific value. To do so, we exploit a shock that is exogenous to the scientific value of a paper, namely the ending time of editorial appointments of colleagues of a paper's author(s). We show that during the course of an editor's appointment, the citation rates of her papers in the journal she edits go up by 23 percentage points. During the same period, these articles don't have any significant citation premium at other journals. The citation premium fades away when the editor steps down. The same phenomenon applies to colleagues of the editor. This provides a counterexample to the null hypothesis that is both large in size and in the population of papers that is affected.

Book Description
Aquesta tesis tracta sobre les diferències en la productivitat agregada del treball entre diferents economies. Gran part de la diversitat en rendes que observem entre països té a veure amb les diferències en productivitat. Per tant, sembla clar que part del patiment humà podria ser alleugerit augmentant l'eficiència en la producció. Aquest objectiu requereix tenir una idea qualitativa i quantitativa de les barreres que ens separen del seu assoliment. Evidentment, la productivitat ha sigut quelcom estudiat pels economistes d'ençà l'Economia inicià el seus passos. No obstant, malgrat la seva importància, o potser precisament per a la seva importància, aquesta àrea de recerca encara ofereix un gran marge d'exploració. En els següents capítols tractaré aquest tema des de diversos angles i utilitzant diferents tècniques però sempre amb el mateix objectiu. El primer capítol, titulat Comptabilitat en el Desenvolupament i Béns Intermedis, gira entorn a la pregunta de si els béns intermedis són part important en explicar les diferències, relatives i agregades, en la productivitat entre països. Tres observacions suggereixen que així és: (i) els béns intermedis són relativament més cars en els països pobres; (ii) les indústries productores de béns demanden béns intermedis amb més intensitat que aquelles que produeixen serveis; (iii) les indústries productores de béns són més prominents com a oferents de béns intermedis en els països pobres. Construeixo un model de creixement multisectorial estàndard que té en compte els tres fets anomenats anteriorment per mostrar que la producció ineficient de béns intermedis afecta negativament la productivitat agregada i augmenta la ràtio de preus entre béns i serveis. Aplicant el model a les dades dels països de renda mitjana i alta, trobo que aquells països més pobres tan sols són una mica més ineficients produint béns que serveis però, en canvi, són molt ineficients produint béns intermedis respecte béns finals i serveis. Si tots els països tinguessin la mateixa eficiència produint béns intermedis que té l'economia d'EE.UU., el model prediu que la diferencia de productivitat entre entre els països de renda més baixa i els de renda més alta, de la mostra, es reduiria en gairebé dos terços mentre les diferencies en el ràtio de preus finals entre països pràcticament desapareixeria. El segon capítol, titulat Delegació de Gestió i Productivitat Agregada, proposa un nou mecanisme per explicar perquè les empreses dels països de renda baixa estan mal gestionades, i quantifica la pèrdua de productivitat resultant. Primer, presento evidència empírica sobre la significativa correlació entre la proporció de treballadors dedicats a la gestió i les garanties de compliment de contractes entre països. En segon lloc, construeixo un model tractable que captura els avantatges de delegar tasques en grans organitzacions. En el model també té lloc un problema de risc moral entre el propietari de la companyia i els gestors de la mateixa. Quan les garanties contractuals no son efectives, és a dir, quan els gestors poden apoderar-se de rendes empresarials, això limita la capacitat de la companyia per créixer i arribar al nivell òptim de gestors. En tercer lloc, utilitzo una versió calibrada del model per a mesurar l'efecte de reduir les garanties per al compliment de contractes. Comparat amb la referència en el nivell de garanties contractuals d'EE.UU., cap tipus de garantia redueix la proporció agregada de gestors en 10 punts percentuals, caracteristic de països amb un nivell de renda d'un desè respecte EE.UU. La pèrdua associada en productivitat es, aproximadament, de 18 punts percentuals. Estadístics addicionals sobre la mida mitjana de les empreses, l'autoocupació i la dispersió de la productivitat ofereixen validació addicional dels resultats. El tercer capítol, titulat Imposició Progresiva i Productivitat Agregada i escrit conjuntament amb en Tomaz Cajner, ofereix una teoria sobre com la imposició progressiva del treball pot afectar la decisió individual d'esdevenir emprenedors o ser treballadors assalariats. Els emprenedors viuen en un entorn amb friccions per a la recerca d'empreses. Un cop fet l'emparellament, s'assumeix una negociació sobre els beneficis del mateix. Quan els impostos són més progressius, aquells projectes més arriscats esdevenen menys lucratius i, per tant, la cua dreta de la distribució dels ingressos es redueix. S'utilitza el model per entrellaçar tres fenòmens macroeconomics importants que han tingut lloc les ultimes dues o tres dècades en els països desenvolupats: el descens de la imposició marginal del treball per les rendes més altes, l'augment de la desigualtat i la reobertura de l'escletxa de productivitat entre EE.UU. i Europa. Una versió parametritzada del model és capaç de generar els dos últims fets com a resultat d'un descens de la imposició sobre el treball de les rendes més altes. No obstant, els resultats quantitatius del model no estan d'acord amb les dades observades.

Book Description
Essays on Microeconomics and Industrial Organisation aim to serve as a source and work of reference and consultation for the field of Microeconomics in general and of Industrial Organisation in particular. Traditionally, Microeconomics is essentially taught as theory and hardly ever an estimation of a demand, production and cost function is offered . Over the last two decades, however, Microeconomics has greatly broadened its field of empirical application. Therefore, this text combines microeconomic theories with a variety of empirical cases. The standardised microeconomic analysis of demand, production and costs is set forth along with appropriate econometric techniques. The text consists of four parts: Demand, Production and Costs (Supply), Market and Industrial Structure and Failure of Market and Industrial Regulation. It includes eleven new chapters with respect to the first edition.

Book Description
How did the big banks get away with so much for so long? Why are so many aged-care residents malnourished? And when did arms manufacturers start sponsoring the Australian War Memorial? In this passionate essay, Richard Denniss explores what neoliberalism has done to Australian society. For decades, we have been led to believe that the private sector does everything better, that governments can’t afford to provide the high-quality services they once did, but that security and prosperity for all are just around the corner. In fact, Australians are now less equal, millions of workers have no sick leave or paid holidays, and housing is unaffordable for many. Deregulation, privatisation and trickle-down economics have, we are told, delivered us twenty-seven years of growth ... but to what end? In Dead Right, Denniss looks at ways to renew our democracy and discusses everything from the fragmenting Coalition to an idea of the national interest that goes beyond economics. ‘Neoliberalism, the catch-all term for all things small government, has been the ideal cloak behind which to conceal enormous shifts in Australia’s wealth and culture ... Over the past thirty years, the language, ideas and policies of neoliberalism have transformed our economy and, more importantly, our culture’ —Richard Denniss, Dead Right
