A Longitudinal Analysis of Cars, Transit, and Employment Outcomes

Access to cars and transit can influence individuals’ ability to reach opportunities such as jobs, health care, and other important activities. While access to cars and public transit varies considerably across time, space, and across populations, most research portrays car access as a snapshot in time; some people have a car and others do not. But does this snapshot approach mask variation in car ownership over time? And how does access to particular types of transportation resources influence individuals’ economic outcomes? The authors improve upon existing research by using panel data from 1999 to 2013 from the Panel Study of Income Dynamics (PSID) to examine levels of automobile access in groups that have variable access: poor families, immigrants, and people of color. They further employ two new national datasets of access to jobs using public transit. These datasets are used to examine the effect of transit and automobile access on income growth over time within families, controlling for a number of relevant variables. The research found that for most families, being “carless” is a temporary condition. While 13% of families in the US are carless in any given year, only 5% of families are carless for all seven waves of data examined in the analysis. The research also found that poor families, immigrants, and people of color (particularly blacks) are considerably more likely to transition into and out car owner-ship frequently and are less likely to have a car in any survey year than are non-poor families, the US-born, and whites. The research also found that improving automobile access is associated with a decreased probability of future unemployment and is associated with greater income gains. However, the analysis suggests that the costs of owning and maintaining a car may be greater than the income gains associated with in-creased car ownership. The relationship between public transit and improved economic outcomes is less clear. The research found that living in areas with access to high-quality public transportation has no relationship with future earnings. However, transit serves an important purpose in providing mobility for those who cannot or choose not to own a car

The Clustering of Organizational Innovation: Developing Governance Models for Vertical Integration

This case explores a cluster of firms that emerged sharing a particular ownership structure. Typically, clusters are thought of as interrelated firms that produce similar products and services. However, we document the emergence and evolution of a cluster of entrepreneurial ventures that developed using a unique governance structure. We explore the deviant case of Renville, MN because of its notable success in developing a series of entrepreneurial ventures that provided producers with the opportunity to vertically integrate.collective entrepreneurship, organizational innovation, joint vertical innovation, cluster, Agribusiness, Research and Development/Tech Change/Emerging Technologies, Q10, Q13, Q16,

Capital Account Liberalization and Economic Performance: Survey and Synthesis

This paper reviews the literature on the effects of capital account liberalization and stock market liberalization on economic growth. The various empirical measures used to gauge the presence of controls on capital account transactions as well as indicators of stock market liberalization are discussed. We compare detailed measures of capital account controls that attempt to capture the intensity of enforcement with others that simply capture whether or not controls are present. Our review of the literature shows the contrasting results that have been obtained. These differences may reflect differences in country coverage, sample periods and indicators of liberalization. In order to reconcile these differences, we present new estimates of the effects on growth of capital account liberalization and stock market liberalization. We find some support for a positive effect of capital account liberalization on growth, especially for developing countries.

On the Joint Distribution of Energy Levels of Random Schroedinger Operators

We consider operators with random potentials on graphs, such as the lattice version of the random Schroedinger operator. The main result is a general bound on the probabilities of simultaneous occurrence of eigenvalues in specified distinct intervals, with the corresponding eigenfunctions being separately localized within prescribed regions. The bound generalizes the Wegner estimate on the density of states. The analysis proceeds through a new multiparameter spectral averaging principle
