Testing the Gender Role-Perception Theory: A Proposed Explanation for the Lack of Maternity Leave Policy in the United States

The United States is the only industrialized country in the world to not have a federally mandated paid maternity leave. While there is an obvious lack of maternity leave policy in the United States, there is not adequate explanation of this lack. There are some current theories used to explain this problem, such as Hofstede’s theory of individualism, and historical influence, but they are not able to fully explain why there is not maternity policy in the United States. A new proposed theory, the Gender Role-Perception Theory combines gender roles in the United States and attitudes/perceptions towards working mothers to explain how society’s negative views of working mothers who abandon their traditional gender roles leads to the unavailability of maternity policy. Results indicated that while the Gender Role-Perception Theory did not predict attitudes towards a federally mandated maternity leave in general, it did predict attitudes towards paid federally mandated maternity leave. Additional findings included males being more supportive of maternity leave than females, and a liberal political affiliation being significantly correlated with attitudes towards a federally mandated maternity leave

Nonlinear Receding-Horizon Control of Rigid Link Robot Manipulators

The approximate nonlinear receding-horizon control law is used to treat the trajectory tracking control problem of rigid link robot manipulators. The derived nonlinear predictive law uses a quadratic performance index of the predicted tracking error and the predicted control effort. A key feature of this control law is that, for their implementation, there is no need to perform an online optimization, and asymptotic tracking of smooth reference trajectories is guaranteed. It is shown that this controller achieves the positions tracking objectives via link position measurements. The stability convergence of the output tracking error to the origin is proved. To enhance the robustness of the closed loop system with respect to payload uncertainties and viscous friction, an integral action is introduced in the loop. A nonlinear observer is used to estimate velocity. Simulation results for a two-link rigid robot are performed to validate the performance of the proposed controller. Keywords: receding-horizon control, nonlinear observer, robot manipulators, integral action, robustness

Credit Constraints and Productivity in Peruvian Agriculture

This paper evaluates the performance of a rural credit market in Peru. We develop a model that shows that collateral requirements imposed by lenders in response to asymmetric information can lead not just to quantity rationing but also to transaction cost rationing and risk rationing. Just like quantity rationing, these two additional forms of non-price rationing adversely affect farm resource allocation and productivity. We test the insights of the model using a panel data set from Northern Peru. We estimate the returns to productive endowments for constrained and unconstrained households using a switching regression model. We find that, consistent with the theory, productivity is independent of endowments for unconstrained households but is tightly linked to endowments for constrained households. We estimate that credit constraints lower the value of agricultural output in the study region by 26%.Financial Economics, International Development,

RISK, WEALTH AND SECTORAL CHOICE IN RURAL CREDIT MARKETS

We develop a model of sorting and matching between borrowers and lenders across formal and informal credit markets in a developing country context. We highlight the role of risk both on credit access and sectoral choice. We examine how activity and sectoral choice vary across agents with heterogeneous wealth endowments.International Development,

Risk Rationing and Activity Choice in Moral Hazard Constrained Credit Markets

This paper explores the productivity and income distribution e.ects of asymmetric information and risk preferences on the credit market. A model of contract design in the presence of moral hazard is developed in which competitive, risk neutral lenders o.er contracts to risk averse agents who hold the option to invest capital and labor time in an entrepreneurial activity. The model gives rise to the potential for quantity rationing and an additional form of non-price rationing called risk rationing. Both quantity and risk rationed agents would seek credit and carry out the entrepreneurial activity in a first best, or symmetric information world. When information is asymmetric, the menu of available loan contracts shrinks. In equilibrium, neither type of agent ends up with a loan contract, and both undertake a safe, but low return wage labor activity. Quantity rationed agents are involuntarily excluded from the entrepreneurial activity because they are denied any loan contract. Risk rationed agents voluntarily retreat from the credit market and the entrepreneurial activity rather than choose among the limited set of high risk contracts available to them in the presence of asymmetric information. Analysis shows that both quantity and risk rationing are likely to be wealth-biased, inhibiting the activity choice and the income earning potential of low wealth agents, and reproducing initial inequality.

Underwriting area-based yield insurance to crowd-in credit supply and demand

Recent theoretical and empirical evidence suggests that risk (especially covariant risk that is correlated across producers) may discourage both the supply of agricultural credit and the willingness of small holders to utilize available credit and enjoy the higher expected incomes credit could make available to them. One possible resolution to this problem is to remove risk from the system by independently insuring it. However, conventional (all hazard) crop insurance has in almost every instance been rendered financially unsustainable by moral hazard and adverse selection problems. This paper instead analyzes two index-based insurance schemes, one based on a weather index, and a second based on measured average yields. While these index insurance products do not protect the farmer from all risks, our econometric analysis (which is based on data from the north coast of Peru) shows that they could have substantial value to the producer and could also crowd-in credit supply from lenders reluctant to carry too much covariant risk in their loan portfolios. We also show that insurance based on measured yields is markedly superior to a weather index (for both borrowers and lenders). We close by arguing that present and past public good failures justify public intervention in this area, and analyze the feasibility of a public scheme to initially underwrite the costs and uncertainties associated with area-based yield insurance

PROJECTED CASH FLOWS AND PROFITABILITY FOR REPRESENTATIVE LOUISIANA FARMS, 2001.

Changes in commodity prices and input costs along with adjustments in capital structure significantly affect farm cash flow requirements and whole farm profitability. These changes coupled with crop yield and price variability increase the need for farm business cash flow and profitability planning on a whole farm basis. Planning for profits is expected to affect both the short and long run success of the business and cash flow planning is expected to allow the manager to establish farm business cash needs for a specified period of time (production period) so that cash commitments are met as they come due. Furthermore, agricultural lenders have become increasingly concerned with loan repayment capacity and are placing relatively more emphasis on cash flow analysis in the loan evaluation process. In general, farm managers who develop cash flow and profitability projections should find it easier to justify and to secure adequate financing for their businesses. The purpose of this report is to supplement the series of annual cost projections for enterprises by providing profitability and cash flow projections for several whole farm situations throughout the state. Whole farm projections of returns and expenses are expected to provide information regarding the relative profitability of individual farming situations throughout the state. Estimates from cash flow projections provide information concerning the timing of cash flows and the distribution of cash flows for individual farm situations and comparison of estimates for these situations provide an indication of the relative cash flow positions of farms across the state. These projections are expected to be of value to farmers, agricultural credit agencies, extension personnel, researchers, and other professionals with an interest in the agricultural production industry. This report is organized into three general parts. Data sources and procedures used in the study are presented in the first section. In the second section, projected income and cash flow statements for representative farms in major crop producing areas of the state are presented and discussed. The final section summarizes the financial projections for representative farms considered in the study.Farm Management,
