...Authority, Incentives and Performance: Theory and Evidence from a Chinese Newspaper Yanhui Wu London School of Economics Job Market Paper February 2011 Abstract Authority de…nes the formal structure of an organization, and is essential for the allocation of resources inside the …rm. This paper develops a theory of authority in a multiple layer hierarchy, in which the distribution of authority alleviates incentive incompatibilities. To examine the theory, I collect monthly personnel data from about 200 journalists over three years in a Chinese newspaper, and provide evidence on their incentives and performance under two basic organizational forms — centralization and decentralization. Relying on an unexpected organizational reform from decentralizing to centralizing editorial power in some divisions of the newspaper, I …nd three main results: 1) centralization improves the quality of the journalists’performance, in terms of the newspaper’ inters nal assessment and the external measures of news content; 2) centralization reduces the journalists’activities for private gain; 3) centralization decreases the editorial activities conducted by managing editors. These results are in line with the theory: a more centralized hierarchy achieves better control over workers’ opportunistic behaviour, at the cost of depressing middle managers’initiative. Key Words: Authority, Organizational Structure, Incentives, Information, Action Distortion, Decision Bias, Media Bias JEL Classi…cations:...

...1 Introduction Governments facing scal pressure have increasingly turned to proposals to create or enhance consumer choice for public services (see, e.g., Besley and Ghatak 2003, Blochliger 2008, Hoxby 2003, Le Grand 2003). In health care, choice is a popular reform model adopted by administrations of dierent political orientations in many countries, including the US, the UK, Denmark, Italy (Lombardy), the Netherlands, Germany and Sweden. The belief is that by increasing choice for patients, providers of care or insurers will become more responsive to patient demand, which in turn will drive greater eciency in the delivery and funding of health care. However, whether enhanced patient choice will make hospital choice more responsive to quality is not well established, although the consequences of poor quality in health care can be dire. Patients' health can be severely compromised by poor quality care, including, as we show below, an increased risk of death. Thus there is a need to understand the responses of health care consumers when they are oered more choice. This is exactly the issue we address here. To do this we exploit a reform which introduced patient choice and tie this to the estimation of a structural demand model that explicitly incorporates the institutional features of the reform. This enables us to identify the eect of increasing choice on patient behavior. We use the model to quantify the gains from the reform in terms of patient welfare and...

...Crime, Transitory Poverty, and Isolation: Evidence from Madagascar Marcel Fafchamps University of Oxford y Bart Minten Cornell Universityz June 2005 Abstract This paper investigates the relationship between poverty and crime. Following a disputed presidential election, fuel supply to the highlands of Madagascar was severely curtailed in early 2002, resulting in a massive increase in poverty and transport costs. Using original survey data collected in June 2002 at the height of the crisis, we …nd that crop theft increases with transitory poverty. Theft thus appears to be used by some of the rural poor as a risk coping strategy. Increased transport costs led to a rise in cattle and crop theft, con…rming earlier …ndings that, in Madagascar, geographical isolation is associated with certain forms of crime. We also …nd that an increase in law enforcement personnel locally reduces cattle theft which, in Madagascar, is a form of organized crime.

...The Long-Term Labor Market Consequences of Graduating from College in a Bad Economy* Lisa B. Kahn Yale School of Management First Draft: March, 2003 Current Draft: August 13, 2009 Abstract This paper studies the labor market experiences of white male college graduates as a function of economic conditions at time of college graduation. I use the National Longitudinal Survey of Youth whose respondents graduated from college between 1979 and 1989. I estimate the e¤ects of both national and state economic conditions at time of college graduation on labor market outcomes for the …rst two decades of a career. Because timing and location of college graduation could potentially be a¤ected by economic conditions, I also instrument for the college unemployment rate using year of birth (state of residence at an early age for the state analysis). I …nd large, negative wage e¤ects to graduating in a worse economy which persist for the entire period studied. I also …nd that cohorts who graduate in worse national economies are in lower level occupations, have slightly higher tenure and higher educational attainment, I am grateful for helpful comments from George Baker, Dan Benjamin, James Heckman, Caroline Hoxby, Larry Katz, Kevin Lang, Fabian Lange, Steve Levitt, Derek Neal, Chris Nosko, Emily Oster, Yona Rubenstein, Hugo Sonnenschein, Mike Waldman and seminar participants at Harvard University, the University of Chicago, Yale University, and the Midwest Economic Association 2003...

...Thieves, Thugs, and Neighborhood Poverty David Bjerk Robert Day School of Economics and Finance Claremont McKenna College 500 East Ninth Street, Claremont CA 91711 Ph: 909-607-4471 david.bjerk@cmc.edu April 25, 2010 Abstract This paper develops a model of crime analyzing how such behavior is associated with individual and neighborhood poverty. The model shows that even under relatively minimal assumptions, a connection between individual poverty and both property and violent crimes will arise, and moreover, "neighborhood" e¤ects can develop, but will di¤er substantially in nature across crime types. A key implication is that greater economic segregation in a city should have no e¤ect or a negative e¤ect on property crime, but a positive e¤ect on violent crime. Using IV methods, I show this implication to be consistent with the empirical evidence. Keywords: Crime; Segregation; Neighborhood E¤ects; Instrumental Variables; Poverty. 1 “I don’ care if I got money, or work Monday through Friday. I just go shoot a t motherf*@#er on the weekends.

...Asymmetric Information, Portfolio Managers, and Home Bias Wioletta Dziuda Jordi Mondria Kellogg School of Management UNC Chapel Hill February 2012 First version: February 2009 Abstract We propose a model of delegated asset management that can explain the following empirical regularities observed in international markets: (i) the presence of home bias, (ii) the lower proportion of mutual funds investing domestically, and (iii) the higher ability and market value of mutual funds investing domestically. In the model, heterogeneous fund managers choose whether to specialize in domestic or foreign assets. Individual investors are uncertain about managers’abilities to generate abnormal returns, and they are more informed about domestic markets than foreign markets. As a result, they are better able to evaluate the ability of managers who specialize in domestic assets. This makes domestic investments less risky and generates home bias. Home bias is magni…ed by the managers’specializations: since ability is rewarded more in the domestic market, higher ability managers invest domestically, making domestic assets more attractive to the investors.

Peter Nearyz University of Oxford and CEPR December 13, 2010 Abstract In this chapter we present a selective analytic survey of some of the main results of trade under oligopoly. We concentrate on three topics: oligopoly as an independent determinant of trade, as illustrated by the reciprocal-markets model of Brander (1981); oligopoly as an independent rationale for government intervention, as illustrated by strategic trade and industrial policy in the third-market model of Spencer and Brander (1983); and the challenges and potential of embedding trade under oligopoly in general equilibrium as illustrated by the GOLE model of Neary (2002).

...Int. J. of Human Resource Management 12:2 March 2001 299–310 Strategic human resource management effectiveness and rm performance Orlando C. Richard and Nancy Brown Johnson Abstract This study tests whether strategic human resource management (SHRM) effectiveness signi cantly affects organizational level outcomes. Using the resource-based view of the rm, this study examines the effective use of human capital on organizational performance. Further, the role that a contextual factor – capital intensity – plays in modelling is explored. Results show that SHRM effectiveness signi cantly reduces employee turnover and increases overall market performance assessment. However, SHRM effectiveness affected both rm productivity and return on equity only when moderated by capital intensity. Keywords Human resources; strategy; effectiveness; outcomes. The interest of strategic management in examining the role of human resources as value-added has evolved (Baird and Meshoulam, 1988) to broaden the focus of human resource management research from a micro (i.e. individual effectiveness focus) approach to a macro (i.e. organizational effectiveness focus) or strategic approach (Butler et al., 1991). The strategic human resource management perspective (SHRM) makes evident the importance of human resource practices for organizational performance, such as employee turnover, productivity and nancial performance. The current focus on HRM as integral to rm’s strategic processes involves viewing...

...Hsu The Heroic Pattern in Life of Pi 95 The Heroic Pattern in Life of Pi Hui-Fen Hsu Applied English Department National Taichung University of Science and Technology Lecturer Abstract This paper examines the universal structure of a mythological hero’s adventure in Life of Pi. The theory is based on Joseph Campbell’s The Hero with a Thousand Faces, which illustrated and distilled heroic patterns from various cultures. The hero’s journey has three stages: separation, initiation, and return. Answering a call to adventure, the hero departs from his familiar world and ventures into a region of supernatural wonder. Miraculous forces are encountered there and a decisive victory is won. He then returns from this mysterious land, bringing an elixir to bene¿t his fellow men. Through this journey of trials, the hero transforms his former self and achieves spiritual growth. Such heroes range from monster slayers to spiritual leaders such as the Buddha and Christ. Life of Pi is a fantasy adventure novel about an Indian boy who survives a shipwreck by drifting on a lifeboat with a tiger. His adventure ¿ts Joseph Campbell’s hero archetype. Similar to the mythological hero, Pi departs from his familiar land of India, answering the call for adventure to a new country. Protected by the supernatural powers of Hinduism, Catholicism, and Islam, he penetrates the dangerous and mysterious realm of the Pacific Ocean. After experiencing harsh ordeals, he returns to the...
