Analysis of long-term prices of micronutrient-dense and starchy staple foods in developing countries
(2022) Alioma, Richard; Zeller, Manfred; Ling, Yee Khor
The continued price increase in food commodities has long been a concern to academia and policymakers because of its substantial impact on poor consumers. Existing literature has concentrated on the cost of micronutrient-dense and starchy staple foods and the price rise in different commodities. Yet, the long-term price growth of micronutrient-dense and starchy staple foods and the price growth gap between micronutrient-dense foods and starchy staple foods have not been given much attention. The paper aimed to estimate the long-term trends in prices and volatility of micronutrient-dense and starchy staples and identify factors that have sustained the growth in prices of food commodities in developing countries. We have used the autoregressive and panel autoregressive distributed lag models to analyse the trends in relative prices and the effects of income growth. The results showed that micronutrient-dense food prices in real terms grew on average by 0.03% per month more than starchy staple food prices, with the expectation of a 12% growth gap in the next 30 years. The volatility of micronutrient-dense food items exceeds starchy staple foods in most domestic markets. Also, the prices of micronutrient-dense foods were more volatile in international markets than in most developing countries. Income growth in developing countries was one of the factors that contributed to the declining relative price of micronutrient-dense food commodities. Other factors, such as the high production of staple foods and their price stabilization policies, may have caused price trends to persist. Policies that enhance price stabilization for micronutrient-dense foods, supplementation, fortification, dietary diversity, and nutrition-sensitive interventions such as biofortification may be adopted in developing countries.
Animal welfare in non-anthropocentric cost-benefit analysis and social welfare functions: A critical review to guide practical application
(2024-10) Dusel, Sara; Wieck, Christine
Cost-benefit analysis and social welfare functions are two closely related methods to evaluate impacts of policies on humans (producers, consumers etc.) and animals. In cost-benefit analysis, the impacts on animals are currently either disclosed as intangible impacts or monetised from the human (anthropocentric) perspective through production costs, revenues and willingness to pay. Social welfare functions are more flexible to aggregate and trade-off impacts on animals, but they are not yet applied in practice. In the literature, advances have been made to monetise policy impacts from the animals’ (non-anthropocentric) perspective and to include animals in social welfare functions. Yet, policy analysts who seek to implement any of these approaches in practice face substantial challenges because the available studies differ considerably in the methodologies and underlying normative assumptions. We conduct a critical review of the scientific and grey literature with the aim to synthesise the available material, to facilitate an informed debate on conflicting normative assumptions, and to eventually guide the practical application of non-anthropocentric cost-benefit analysis and social welfare functions. The results of the critical review are presented in the form of a checklist that allows to better comprehend key steps of the methodologies. Step-by-step, the checklist gives an overview of the alternative options and normative assumptions in the literature, and points to any remaining research gaps. Beside the academic debate, this is relevant for practical policy analysts who need to make methodological choices for their policy questions at hand.
Animal welfare in non-anthropocentric cost-benefit analysis and social welfare functions: a critical review to guide practical application
(2025) Dusel, Sara; Wieck, Christine
Cost-benefit analysis and social welfare functions are two closely related methods to evaluate policy impacts. In this critical review, we present the state of knowledge on how to include the animals’ (non-anthropocentric) perspective in these policy evaluations. For this, we synthesize material from the scientific and grey literature and develop a checklist that guides through the process of non-anthropocentric cost-benefit analysis and social welfare functions. Step-by-step, the checklist gives an overview of the alternative options and normative assumptions in the literature and points to remaining research gaps.
Incentives to enforce and stimulate
microeconometric evidence from natural experiments
(2020) Treber, Lukas; Dwenger, Nadja
Incentives can be powerful tools to enforce behavior and to stimulate and steer the economy. However, due to the complexity of how incentives are perceived by economic agents, designing effective incentive structures is difficult. A better understanding of incentives enables policymakers to design such policies, ultimately increasing overall well-being. This thesis advances our knowledge on how incentives work, how they change behavior, and how to effectively use them.
Social capital from an individual perspective
(2018) Neidhardt, Jan; Ahlheim, Michael
Three contributions to the social capital literature are presented in this thesis: Firstly, a concept of social capital that is compatible with the individual perspective prominent in neoclassical economics is identified. Secondly, a new tool to measure individual social capital is developed and applied. Thirdly, results on the distributional effects of a great number of predictors on individual level social capital are obtained and discussed for a representative sample of the German resident population.
Trade and welfare effects of a potential free trade agreement between Japan and the United States
(2022) Walter, Timo
This paper addresses the trade and welfare implications of a bilateral trade agreement between the U.S. and Japan. In 2019, the two countries signed a “stage one” trade agreement, with the U.S.-Japan Trade Agreement (USJTA) and the U.S.-Japan Digital Trade Agreement as two small trade agreements. A comprehensive bilateral free trade agreement (FTA) is currently under discussion between Washington and Tokyo, with the U.S. government alternatively joining the Comprehensive and Progressive Agreement for the Trans-Pacific Partnership (CPTPP). Based on the theoretical model of Caliendo and Parro (Rev Econ Stud, 82(1):1–44, 2015) , I analyze the welfare gains of such a bilateral FTA in the style of Aichele et al. (Where is the value added? China’s WTO entry, trade and value chains, ZBW-Deutsche Zentralbibliothek für Wirtschaftswissenschaften, Leibniz, 2014). I simulate trade and welfare impacts for the USJTA and the U.S.-Japan Digital Trade Agreement, as well as for a deep bilateral FTA. In addition, I examine and compare the welfare implications of the established CPTPP with the scenario of the U.S. or China joining CPTPP. My findings show that Japan’s welfare increases by 0.3% and U.S. welfare increases by 0.14% as a result of the FTA. Welfare of both countries would increase if the U.S. entered CPTPP, with Japanese welfare being even higher if China acceded to CPTPP.
The volatility of housing prices: Do different types of financial intermediaries affect housing market cycles differently?
(2024) Braun, Julia; Burghof, Hans-Peter; Langer, Julius; Sommervoll, Dag Einar
Housing markets display several correlations to multiple economic sectors of an economy. Their enormous impact on economies’ health, wealth, and stability is uncontroversial. Interestingly, the forms of financing residential property vary widely between the different countries in terms of both, the available product types and the institutions offering them. This research examines the implications of different financial intermediaries on housing market cycles with special emphasis on two institutional types, conventional banks and building and loan associations. Introducing a heterogeneous agent-based model, the interactions of buyers, sellers, and the two types of credit institutions are assessed. Heterogeneous economic principles and expectations of agents create endogenous market conditions which are strongly influenced by the lending practices of financial intermediaries. Focusing primarily on collateral values to decide about lending, conventional banks may contribute to volatile housing markets which are prone to recessions. Building and loan associations, on the other hand, rely to a greater extent on endogenously created borrower information. Thus, they are able to cushion the volatility of house prices caused by procyclical mortgage lending of conventional banks and increase the stability of the housing market. Simulations show that the most stable market conditions are attained if both types of financial intermediaries serve the mortgage lending market jointly. Furthermore, transaction and homeownership rates are the highest in this market setting. These findings advocate in favor of diversified financial markets.
