Linked general equilibrium economic and ecological models are connected through agricultural runoff and the fisheries. They are applied to a North Carolina estuary in which agricultural runoff alters phytoplankton densities and the resulting hypoxia leads to diminished fisheries. The effects of hypoxia on multiple species across space are analyzed and the joint economic and ecosystem wide respo...

In traditional economic models, individual utility depends only on absolute consumption. These models lie at the heart of claims that pursuit of individual self-interest promotes aggregate welfare. Recent years have seen renewed interest in economic models in which individual utility depends not only on absolute consumption, but also on relative consumption. In contrast to traditional models, t...

In August 1996, the Personal Responsibility and Work Opportunity Reconciliation Act (P.L. 104-193; PROWRA) was signed into law ending a 60-year federal entitlement guaranteeing families a basic level of assistance during periods of economic hardship. Evaluations and policy studies examining the impact of welfare reform, as implemented through the Temporary Assistance for Needy Families (TANF) P...

Has greater investment in education and research and development (R&D) a positive impact on economic welfare? We analyzed this question using the Weka machine learning and data mining systems. We collected data from the statistical databases for the year 2001. The obtained classification trees show that the level of participation in higher levels of education has a high impact on economic welfa...

This paper investigates the relationship between fluctuations in economic growth, unemployment, and voting along a left–right axis. I estimate a model that explains how political fluctuations are caused by economic fluctuations in the OECD countries. I find that higher economic growth causes a shift to the left of policy sentiments. I hold the provision of social insurance by the welfare state ...

Social choice theory is concerned with the evaluation of alternative methods of collective decision-making, as well as with the logical foundations of welfare economics. In turn, welfare economics is concerned with the critical scrutiny of the performance of actual and/or imaginary economic systems, as well as with the critique, design and implementation of alternative economic policies. The Ha...

This paper develops an endogenous growth model with spillovers of public goods, Leviathan taxation, and mobile capital to examine the relative merits of centralized and decentralized fiscal systems for economic growth and social welfare. We show that a decentralized system dominates a centralized system in terms of economic growth; however, the difference in social welfare between a decentraliz...

With the rapid growth of wireless access networks, various providers offer their services using different technologies such as Wi-Fi, Wimax, 3G, 4G and so on. These networks compete for the scarce wireless spectrum. The spectrum is considered to be a scarce resource moderated by the spectrum allocation regulatory (“regulatory” for short) which is the governance body aiming to maximize the socia...

In the last two decades, the European welfare states have been criticised for failing to address problems of unemployment and poverty. It is also claimed that Western welfare statism is too expensive, and that it has harmed economic development (Feldstein, 1974; Mishra, 1984, 1990; Pierson, 1995; Buti, Franco & Pench, 1999). In many industrial countries, government programmes have been trimmed ...
