Assessing The Economic Costs Of Water Pollution In The Yangtze River, China, Xiaoli Zhang

Journal of Ocean and Coastal Economics

Water pollution of the Yangtze River basin is very serious. Studies have shown that from the upper to the lower river, the water volume decreases and development and pollution increase, especially in trans-boundary areas. The Yangtze Estuary is located at the intersection of Jiangsu Province and Shanghai where the waters flow directly into the East China Sea. The estuary provides drinking water to many people and serves multiple other functions, including agricultural irrigation, tourism, and aquaculture. It plays a pivotal role in the local social and economic development and in people’s general wellbeing. Directly or indirectly, the pollution of the …

What Have We Learned From The Deepwater Horizon Disaster? An Economist’S Perspective, Daniel R. Petrolia

Journal of Ocean and Coastal Economics

This paper outlines what we have learned about the impacts of the Deepwater Horizon (DWH) oil disaster from the economics discipline as well as what effect the DWH disaster has had on the economics discipline. It appears that what we know about the economic impact of the DWH spill today is limited, possibly because such analysis is tied up in the federal Natural Resource Damage Assessment (NRDA) process and other state-led efforts. There is evidence, however, that the NRDA process has changed over time to de-emphasize economic valuation of damages. There is also evidence that economists may be producing fewer …

Good Governance Is Good Politics, Ishrat Husain Dr.

Faculty Research - Talks, Speeches, & Discourse

Pakistan has been facing a unique and difficult dilemma for quite some time. Government leaders of the day are unhappy that they are unable to deliver upon the commitments they had made to the electorate at the time of the elections. The political leaders complain that the policy formulation is weak, Policy-Performance Gap is widening every day, and implementation of decisions almost non-existent. The bureaucrats are unhappy that they are not allowed to do their job because of interference by the politicians. The citizens and society are highly disenchanted and dissatisfied as they are unable to access basic services the …

Medicaid And The Labor Supply Of Single Mothers: Implications For Health Care Reform, Vincent Pohl

Upjohn Institute Working Papers

The Patient Protection and Affordable Care Act expands Medicaid and introduces health insurance subsidies, thereby changing work incentives for single mothers. To undertake an ex ante policy evaluation of the employment effects of the PPACA, I structurally estimate a model of labor supply and health insurance choice exploiting existing variation in Medicaid policies. Simulations show that single mothers increase their labor supply at the extensive and the intensive margin by six and five percent, respectively. The PPACA leads to crowding-out of employer-sponsored health insurance of about 40 percent and increases single mothers' welfare by about $190 per month.

The Effect Of Active Video Games On The Heart Rate Of Older Adults, Yeon Bai, Shahla M. Wunderlich, Diane M. Hanel

Department of Nutrition and Food Studies Scholarship and Creative Works

Background: Heart rate is used as a health biomarker. This aim of this study was to investigate the effects of playing active video games on the heart rate of older adults, in comparison to the heart rate after common table recreational activity.

Methods: An experimental study with 40 participants was conducted: a control group (n=20) participated in common Pokeno® card games; an experimental group (n=20) played WiiTM bowling. The participants’ pre- and post-activity heart rates were measured and compared between and within groups using t-tests.

Pak-Afghan Economic Ties, Ishrat Husain Dr.

Faculty Research - Newspaper and Magazine Articles

Several significant developments have taken place in Afghanistan in the past few months that require fresh thinking and a review of the relationship between Pakistan and Afghanistan. First, most of the Nato forces have withdrawn from Afghanistan while the presence of US forces has been considerably reduced and largely limited to support and training of the Afghan National Army. Second, the general elections in Afghanistan were successfully conducted with a large turnout and the majority of the population participated in this peaceful democratic transition. Third, the newly elected President Ashraf Ghani enjoys excellent credentials and is committed to the economic …

Perspectives From China: Social Media And Living Well In A Chinese Context, Sarah Mattice

UNF Faculty Research and Scholarship

The United States has a current population of approximately 313.9 million people. In 2013, more than 600 million users had active accounted on Qzone, China’s largest social media site (Millward 2013). Although discussions of social media tend to assume American or European users, social media is a worldwide phenomenon, and different locales bring different concerns to bear on social media ethics. China not only leads the world in terms of sheer numbers of users, but also has the most active environment for social media, ranging from instant chat platforms like QQ to blogs, microblogs, social networking sites, and gaming platforms. …

Economic Freedom And Public, Non-Market Institutions: Evidence From Criminal Prosecution, Claudio Detotto, Bryan C. Mccannon

Economics Faculty Working Papers Series

Economic freedom, which measures the protection of property and freedom to contract, is generally argued to capture the quality of a state’s institutions regarding market activity. As to be expected, numerous studies have found that economic freedom is associated with good economic outcomes. Additionally, much effort in public economics has worked to identify the features of quality non-market public institutions. No effort has been made to connect institutions that influence market activity and institutions that govern non-market activities. We take a first step. We employ a linear programming method for measuring relative efficiencies known as Data Envelopment Analysis. We apply …

A Simple Solution To The Distance Puzzle: Balanced Data And Poisson Estimation, Roger White, David Buehler

Economics

We propose the use of a balanced panel data set and Poisson regression as a solution to the distance puzzle. Employing annual data for the period 1972–2010, we confirm the existence of the puzzle by applying OLS regression to both an unbalanced panel data set and a narrowly defined balanced panel. We find that Poisson regression remedies the distance puzzle, producing a constant trend for the distance coefficient when the unbalanced panel is examined and a positive trend for the balanced data. The findings confirm the common intuition that the influence of transport costs on trade flows has decreased over …

Robust Multiple Regimes In Growth Volatility, Andros Kourtellos, Ioanna Stylianou, Chih Ming Tan

Economics & Finance Faculty Publications

In this paper, we uncover growth volatility regimes and identify their robust determinants using a large international panel of countries. In doing so, we propose a novel empirical methodology that allows us to simultaneously deal with two key elements of model uncertainty, namely theory uncertainty and parameter heterogeneity, by unifying two recent econometric techniques: Bayesian model averaging and threshold regression. We find ample evidence of parameter heterogeneity and model uncertainty. Our results highlight the role of ethnic fractionalization, institutions, financial development, health, and geography.

Does Defensive Medicine Reduce Health Care Spending?, Scott Barkowski

Publications

The medical community often argues that physician fear of legal liability increases health care spending. Theoretically, though, the effect could be positive or negative, and empirical evidence has supported both cases. Previous empirical work, however, has ignored the fact that physicians face risk from industry oversight groups like state-level medical licensing boards in addition to civil litigation risk. This paper addresses this omission by incorporating previously unused data on punishments by oversight groups against physicians, known as adverse actions, along with malpractice payments data to study state-level health care spending. My analysis suggests that health care spending does not rise …

Unbiased Instrumental Variables Estimation Under Known First-Stage Sign, Isaiah Andrews, Timothy B. Armstrong

Cowles Foundation Discussion Papers

We derive mean-unbiased estimators for the structural parameter in instrumental variables models with a single endogenous regressor where the sign of one or more first stage coefficients is known. In the case with a single instrument, the unbiased estimator is unique. For cases with multiple instruments we propose a class of unbiased estimators and show that an estimator within this class is efficient when the instruments are strong. We show numerically that unbiasedness does not come at a cost of increased dispersion in models with a single instrument: in this case the unbiased estimator is less dispersed than the 2SLS …

Unbiased Instrumental Variables Estimation Under Known First-Stage Sign, Isaiah Andrews, Timothy B. Armstrong

Cowles Foundation Discussion Papers

We derive mean-unbiased estimators for the structural parameter in instrumental variables models with a single endogenous regressor where the sign of one or more first stage coefficients is known. In the case with a single instrument, there is a unique non-randomized unbiased estimator based on the reduced-form and first-stage regression estimates. For cases with multiple instruments we propose a class of unbiased estimators and show that an estimator within this class is efficient when the instruments are strong. We show numerically that unbiasedness does not come at a cost of increased dispersion in models with a single instrument: in this …

Transparency And Distressed Sales Under Asymmetric Information, William Fuchs, Andrzej Skrzypacz

Cowles Foundation Discussion Papers

We analyze price transparency in a dynamic market with private information and correlated values. Uninformed buyers compete inter- and intra-temporarily for a good sold by an informed seller suffering a liquidity shock. We contrast public versus private price offers. In a two-period case all equilibria with private offers have more trade than any equilibrium with public offers; under some additional conditions we show Pareto-dominance of the private-offers equilibria. If a failure to trade by the deadline results in an efficiency loss, public offers can induce a market breakdown before the deadline, while trade never stops with private offers.

Dynamic Mechanisms Without Money, Yingni Guo, Johannes Hörner

Cowles Foundation Discussion Papers

We analyze the optimal design of dynamic mechanisms in the absence of transfers. The designer uses future allocation decisions as a way of eliciting private information. Values evolve according to a two-state Markov chain. We solve for the optimal allocation rule, which admits a simple implementation. Unlike with transfers, efficiency decreases over time, and both immiseration and its polar opposite are possible long-run outcomes. Considering the limiting environment in which time is continuous, we show that persistence hurts.

Estimating The Production Function For Human Capital: Results From A Randomized Control Trial In Colombia, Sarah Cattan, Emla Fitzsimons, Costas Meghir, Marta Rubio-Codina

Cowles Foundation Discussion Papers

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children. We estimate production functions for cognitive and socio-emotional skills as a function of maternal skills and child’s past skills, as well as material and time investments that are treated as endogenous. The effects of the program can be fully explained by increases in parental investments, which have strong effects on outcomes and are complementary to both maternal skills and child’s past skills.

Estimating The Production Function For Human Capital: Results From A Randomized Control Trial In Colombia, Orazio P. Attanasio, Sarah Cattan, Emla Fitzsimons, Costas Meghir, Marta Rubio-Codina

Cowles Foundation Discussion Papers

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of material and time investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, which have strong effects on outcomes and are complementary to both maternal skills and child’s baseline skills.

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents’ material and time investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, emphasizing the importance of parenting interventions at an early age.
