Using data from 1995 and 1996, we estimate the cost of the Arizona Enhanced I/M Program and the emission reductions achieved. We begin by enumerating briefly the components of I/M costs and discuss their size and incidence. Then we describe the empirical information from Arizona and how we use...

The expense and inconvenience of enhanced vehicle emissions testing using the full 240-second dynamometer test has led states to search for ways to shorten the test process. In fact, all states that currently use the IM240 allow some type of fast-pass, usually as early in the test as second 31,...

This paper explores the influence of the behavior of the Forest Service and Bureau of Land Management on effective public policy toward the national forests. It shows that fluctuations in stumpage sales from such forests have been large. Furthermore, those fluctuations could well have a...

In the Philippines, where rice is considered the most important food crop, attempts to influence rice prices have been prevalent. The government, through National Food Authority (NFA) has sought to establish stocks and control imports to stabilize prices since its establishment in 1972 to...

This study highlights some problems with using the Johansen cointegration statistics on data containing a negative moving average (NMA) in the error term of the data generating process. We use a Monte Carlo experiment to demonstrate that the asymptotic distribution of the Johansen cointegration...

Policy intervention in the biofuel market has led to a significant increase in biofuel production and use in the past several years. However, the welfare effect of biofuelpolicies, specifically the ethanol tax credit for corn ethanol, ethanol import tariff andrenewable fuel standard (RFS)...

This dissertation examines three themes of efficiency in fisheries economics and management.The first theme is intertemporal efficiency; by examining fishery managementproblems within a stochastic bioeconomic model, the tradeoffs between current and futureconsumption are clear. The second theme...

Biofuels have been promoted to achieve energy security and as a solution to reducing greenhouse gas (GHG) emissions from the transportation sector. This dissertation presents a framework to examine the extent to which biofuel policies reduce gasoline consumption and GHG emissions and their...
