| A simple two-sector endogenous growth model of government spending and growth is developed with a producing and a lobbying sector. Lobbyists divert government spending for private gains. One key innovation is this: With democratization, information (and power) becomes more diffused (public), allowing more lobbyists to lobby but reducing gains per lobbyist. Thus, aggregate rents rise with the number of lobbyists but fall with increasing competition among them. This simple mechanism produces a "U" curve in which growth falls with early democratization but rises later, and a related "inverted U" curve in which rents rise with early democratization but fall later. Extensive empirical test of the interrelationship between growth, government spending,... |

| Does democratization imply faster growth, less corruption and less inefficiency? Past studies yield ambiguous results on the effects of democracy on economic performance and growth. We develop a simple two-sector endogenous growth model that shows both very young and mature democracies grow faster than countries in mid stages of democratization, producing a 'U' effect. This effect results from the pattern of rent seeking as it diverts from the provision of public goods. Rent-seekers act as monopolistic competitors. Initially, more democracy increases their number, raising aggregate rents. However, rents per rent-seeker fall with the number of rent seekers, aggregate rents fall in mature democracies. Thus, rents show an 'inverted-U' effects in relation to... |

| An overlapping generational model of educational investment in a dual labor markets is presented in which education serves both as a screening device and as investment in human capital. Labor market dualism arises not only via the conventional technology (productivity) differential between a primary and a secondary sector, but also by a higher than a labor market clearing wage in the primary sector, to insure no shirking by the workers (an element shared with the efficiency wage theories). The important determinants of the workers' educational investment decision are the degree of discipline in the labor market and the cost of education. Among the three most commonly discussed educational policies of maximizing the number of the educated, maximizing the... |

| The role of international trade in the new growth theory is investigated from several perspectives. Following a historical outline and a brief analytical sketch of the R&D based models, the results from fitting three structural models to data are presented. Results show the relative impacts on growth from trade and R&D based policies including technological spillovers from trade. The mechanism of inter-sectoral adjustments to the long-run growth path are also discussed. Results from selected econometric studies are reviewed. With emphasis on agriculture, this includes evidence of technological spillovers from trade, the effect of R&D expenditures on growth in total factor productivity, and the extent to which the stock of technological... |

| Using an endogenous growth framework, this paper analyzes the impact of lobbying for public goods on the long run steady-state growth rate of the economy. A socially optimal level of lobbying can be found to exist in the absence of a social planner. Atomistic households, however, exceed this level by viewing taxes as fixed, ignoring the aggregate tax impact of lobbying via increased public expenditures. Two extensions are presented. In one, anti-tax lobbying is analyzed, drawing parallel results. In another, a quasi-public good is introduced, lobbying for which is based not on altruism, but on private gains, though public gains occur as a side effect. |

| Food safety events in the recent past have generated significant media attention and resulted in increased concerns over the food on the plate. A recent study (Degeneffe et al., 2007) on consumer perceptions of bio-terrorism and food safety risks shows increasing concern over food safety and corresponding decreasing confidence in security of the U.S. food supply. While there are some mandated safety and security practices for the firms in the food supply chain the economic incentives for the firms to actively address food safety throughout the supply chain are less clear. Security practices often require significant investments in both within the firm and across the supply chain but do not show tangible returns. Also, higher investments in securing the... |

| Using the Supermarket Panel Data gathered by The Food Industry Center at the University of Minnesota, the behavior of food retailers is examined in their adoption of Information Technologies that facilitate information exchange with suppliers. Using a theoretical framework developed by Mohtadi and Kinsey (MK) (2004) the predictions of that paper are examined. Logistic Regressions based on Maximum Likelihood Estimation support the hypothesis that food retailers with greater market power and numerous suppliers are more inclined to share, rather than to withhold, sales information. Stock-outs play a key role in the process as well. Finally, the structure of the market plays an interesting role in the type of information sharing platforms that the... |
