Professor Emmanuel Ohene Afoakwa

Response surface methodology was used to optimize the processing conditions in the preparation of cowpea tempeh. The independent factors studied were boiling time (varying from 5 to 30 min), incubation time (varying from 12 to 48 h) and incubation temperatures (varying from 25 to 50°C), whereas the dependent factors were protein content, protein solubility, pH, titratable acidity and total color difference (using L, a* and b*). Regression models were generated and adequacy was tested with regression coefficients (R2) and the lack-of-fit tests. Optimum processing conditions were determined by method of superimposition. There was a strong and significant influence (P < 0.01) of the quadratic effect of the incubation time on the protein content of the cowpea tempeh, with similar significance (P < 0.01) noted in protein solubility with increasing boiling time. The optimum processing conditions observed for the preparation of cowpea tempeh were boiling time of about 20 min, incubation time of about 28 h and incubation temperature of about 37°C.

The Redistributive Effects Of Political Reservation For Minorities: Evidence From India, Nishith Prakash, Aimee Chin

Nishith Prakash

We examine the impact of political reservation for disadvantaged minority groups on poverty. To address the concern that political reservation is endogenous, we take advantage of the state-time variation in reservation in state legislative assemblies in India generated by national policies that cause reservations to be revised and the time lags with which revised reservations are implemented. Using data on sixteen major Indian states for the period 1960-2000, we find that increasing the share of seats reserved for Scheduled Tribes significantly reduces poverty while increasing the share of seats reserved for Scheduled Castes has no impact on poverty. Political reservation …

Evaluating Reforms In Canadian Chicken Marketing Mechanisms Using A Linear-Quadratic Inventory Model, Abdessalem Abbassi, Jean-Philippe Gervais

abdessalem abbassi

Marketing institutions in supply managed industries are evolving due to broad globalization pressures. The output and sales decisions of chicken processing firms under two different pricing mechanisms are modeled using a linear-quadratic inventory model. Decision rules lead to structural equations that relate output and sales to their own lagged values, lagged inventories and lagged prices and cost indicators. A Generalized Method of Moments (GMM) estimator is applied to the system of equations. The null hypotheses no adjustment costs in processing and no role for inventories in marketing are rejected. We simulate the impacts of reforming the chicken pricing mechanism, moving …

Compensatory Restoration In A Random Utility Model Of Recreation Demand, George R. Parsons, Ami K. Kang

George Parsons

Natural Resource Damage Assessment cases often call for compensation in non-monetary or restoration equivalent terms. In this paper we present an approach that uses a conventional economic model, a travel-cost random utility model of site choice, to determine compensatory restoration equivalents for hypothetical beach closures on the Gulf Coast of Texas. Our focus is on closures of beaches on the Padre Island National Seashore and compensation for day-trip users. We use a mixed logit site choice model in our application with revealed preference data. Using the random utility model we identify restoration projects (changes in beach characteristics) that pass a …

Effects Of Information About Invasive Species On Risk Perception And Seafood Demand By Gender And Race, Timothy C. Haab, John C. Whitehead, George R. Parsons, Jamie Price

George Parsons

In this paper we consider the effects of negative and positive risk information on perceived seafood risks and seafood consumption by gender and race. The data is from a Mid-Atlantic survey of coastal seafood consumers. We elicit risk perceptions in three risk scenarios with a dichotomous choice with a follow-up question format. We elicit continuous revealed and stated preference seafood consumption in nine risk and price scenarios. Analysis in four gender and race categories indicates that demographic groups respond to the positive and negative information in different ways. Communication of risk information as risk mitigation policy is a challenge.

Measuring The Recreational Use Value Of Migratory Shorebirds: A Stated Preference Study Of Birdwatching On The Delaware Bay, Kelley H. Myers, George R. Parsons, Peter E T Edwards

George Parsons

In this article we estimate the recreational use value of household trips to view shorebirds during the annual horseshoe crab/shorebird migration on the Delaware Bay. We use contingent valuation to estimate the value of day and overnight trips separately and use a discrete choice question followed by a payment-card question to generate our valuation data. Our best estimates for the value of a day trip is about $66 - $90/household and for an overnight trip is about $200 - $425/household (2008$). Our data are from the 2008 season, and our average household size is 1.66. For some context, estimates from …

The Effects Of The 1996 U.S.-Canada Softwood Lumber Agreement On The Industrial Users Of Lumber: An Event Study, Nisha Malhotra, Sumeet Gulati

Nisha Malhotra

In this article, we analyze whether the Softwood Lumber Agreement between the United States and Canada imposed significant economic costs on industries that use softwood lumber in the United States. To ascertain this impact, we use an event study. Our event study analyzes variations in the stock prices of lumber-using firms listed at the major stock markets in the United States. We find that the news of events leading to the Softwood Lumber Agreement had significant negative impacts on the stock prices of industries using softwood lumber. The average reduction of stock prices for our sample of firms was approximately …

Trade Diversion From Tomato Suspension Agreement, Kathy Baylis, Jeffrey M. Perloff

Kathy Baylis

: Trade barriers can cause output to be diverted to other countries and into other products. We study the effect of a voluntary price restraint (VPR) on Mexican tomatoes entering the United States. The diversion caused by the VPR is statistically and economically significant – representing over four-fifths of the direct effects of the trade barrier. When the VPR was binding, Mexico exported more tomatoes to Canada, the United States cut back on exports while Canada increased their exports to the United States. The VPR also diverted fresh tomatoes in Mexico into paste production, which was then exported to the …

A Note On Causal Relationship Between Fdi And Savings In Bangladesh, Mohammad Salahuddin, Muhammad Shahbaz Shahbaz, Muhammad Irfan Chani

Muhammad Irfan Chani

This paper aims to investigate the causal relationship between foreign direct investment and gross domestic savings in Bangladesh over a period of 1985-2007. In doing so, Johansen cointegration technique and error correction methods are employed to examine the long run and short run relationship between foreign direct investment and gross domestic savings. To determine the direction of causality, we used innovation accounting approach. Results suggest that there exist bi-directional causal relationship between foreign direct investment and gross domestic savings but the movement is stronger from domestic savings to foreign direct investment. The result also implies complimentary relationship between them and …
