Abstract

A large literature focuses on the biases of individuals and consumers, as well as "nudges" and other policies that can address those biases. Although policy decisions are often more consequential than those of individual consumers, there is a dearth of studies on the biases of policy professionals: those who prepare and implement policy on behalf of elected politicians. Experiments conducted on a novel subject pool of development policy professionals (public servants of the World Bank and the Department for International Development in the United Kingdom) show that policy professionals are indeed subject to decision making traps, including sunk cost bias, the framing of losses and gains, frame-dependent risk-aversion, and, most strikingly, confirmation bias correlated with ideological priors, despite having an explicit mission to promote evidence-informed and impartial decision making. These findings should worry policy professionals and their principals in governments and large organizations, as well as citizens themselves. A further experiment, in which policy professionals engage in discussion, shows that deliberation may be able to mitigate the effects of some of these biases.

Abstract

In this paper, we analysed the effect of real economic variables in the mutual fund flows assuming that they are the first drivers for a change in the investor behaviour, we tried to replicate some regressions models from the literature and create a new customised ones to serve the purpose of the project thesis.&#13;In parallel, we know that mutual funds are grouped into different categories based on assets with different levels of risk perception (e.g. equity fund, fixed income fund, money market fund) so we tried to create separate models for each category in order to get a better all-around view of the problem.&#13;We made some conclusions regarding the retail investors’ behaviour towards mutual fund industry according to the thesis framework. Hoping that the implementation of the models will be of a great help to the company.

Abstract

Risk aversion has been treated by traditional finance as a stable input that was more useful to match the investors’ needs than a real driver for the financial markets. With the development of behavioural finance, some analysts tried to use this metric to improve their predictions over the markets. However, risk aversion is hard to aggregate. Most early attempts to find a relevant risk aversion of the market as a whole failed.&#13;In the early 2000’s, researchers started focusing on the derivatives markets to improve the measurement of the representative investor’s attitude toward risk. Since hedges are possible over options, they can be used to create risk-neutral market expectations at a maturity. These expectations can be interpreted as probability density function by using different processes. Once these risk neutral density functions are created, it can be compared to the actual view of the representative investor over the market at the same maturity. The variation between the risk-neutral and the subjective densities can be interpreted as a proxy of the marginal rate of substitution at maturity. From this relation, the relative risk aversion of the market can be calculated. &#13;Unfortunately, the process to create the risk neutral density requires consequent amount of data. In this thesis, the focus is done on the creation of a coefficient that can be computed with less statistics. The information is not processed from every option price but from the implied volatility index of an underlying market index. Distribution is parametrized, and the risk aversion can be computed with only two variables per date. However, this simplification is lowering the accuracy of the created coefficient. In the second part of the thesis, the explanatory power of the simplified metric is evaluated through linear regressions. The goal is to assess the impact of the simplification process. &#13;The results are mixed. The created coefficients are able to explain a significant part of the returns of the index. But more could have been expected regarding the fact that this risk aversion metric is using ex-post information.

Abstract

Interventions in highly insecure and fragile contexts are always confronted with the latent risk of not being able to implement the program as intended. Despite its high policy relevance, little is known about the impacts of program disruption or cancellation on beneficiaries. This study uses the unplanned cancellation of the South Sudan Youth Business Start-Up Grant Program to assess the socioeconomic, behavioral, and psychological consequences of a program that fails to be implemented as intended. Originally planned as a randomized trial, the Youth Startup Business Grant Program consisted of an unconditional cash grant combined with a business and life skills training targeting the youth in South Sudan. Due to the intensification of violence in the country, the disbursement of the grant was terminated in late 2016 before most of the intended beneficiaries had accessed the grant. The study uses survey data from face-to-face interviews and experimental data from lotteries, trust games, and a list experiment to assess the consequences of the cancellation in a comprehensive form. The empirical analysis employs instrumental variable regressions to control for individual characteristics that might have made it more likely to access the grant before disbursement was frozen. The results show that participants who received the originally planned treatment displayed significant improvements in their consumption, savings, and psychological well-being. However, participants who vainly expected to receive the cash grant showed reduced levels of consumption and women among this subgroup also experienced strong reductions in their trust level. In addition, the study finds some evidence that these women were less likely to migrate.

Abstract

The paper uses Google mobility data to identify the determinants of social distancing during the 2020 COVID-19 outbreak. The findings for the United States indicate that much of the decrease in mobility is voluntary, driven by the number of COVID-19 cases and proxying for greater awareness of risk. Non-pharmaceutical interventions such as closing nonessential businesses, sheltering in place, and school closings are also effective, although with a total contribution dwarfed by the voluntary actions. This suggests that much social distancing will happen regardless of the presence of non-pharmaceutical interventions and that restrictions may often function more like a coordinating device among increasingly predisposed individuals than repressive measures per se. These results are consistent across country income groups, with only the poorest countries showing limited effect of non-pharmaceutical interventions and no voluntary component, consistent with resistance to abandon sources of livelihood. The paper also confirms the direct impact of the voluntary component on economic activity, by showing that the majority of the fall in restaurant reservations in the United States and movie spending in Sweden occurred before the imposition of any non-pharmaceutical interventions. Widespread voluntary de-mobilization implies that releasing constraints may not yield a V-shaped recovery if the reduction in COVID risk is not credible.

Abstract

Gerbils (Meriones unguiculatus) were allowed to forage during four periods in an environment that contained three bowls; one with sand, the second with 30 sunflower seeds mixed with sand, and the third with just seeds (during period 1) or 250 seeds mixed with sand (during periods 2, 3 and 4). During periods 1 and 2 the animals ate approximately 24 seeds from the 30 bowl. The behavior of working for food while "free food" is present was not influenced by whether or not that food really was "free" or if it was just a question of the amount of work required. During all three stable treatments (1, 2, and 4) the animals began by eating for about 15 min from the 30 bowl and only later changed over to the richest bowl. The big difference in behavior occurred in treatment 3 when the location of the bowls was changed. The animals took significantly less seeds from the 30 bowl (11 seeds), and no pattern like that from 1, 2, and 4 could be found. It is probable that the change in behavior between period 2 and 3 was elicited by the change in certainty of food resources. As the world became more uncertain the animals reduced the explorative part of their behavior and incrased the exploitative part, i.e. they came closer to being short term maximizers. Treatment 4 was equal to treatment 2 and done to control for any learning effects. No such effects were found

Abstract

This paper investigates the patterns of capital entry barriers and capital returns in informal Micro and Small Enterprises (MSE's) using a unique micro data set seven West-African countries. The author's findings support the view of a heterogeneous informal sector that is not primarily host to subsistence activities. While an assessment of initial investment identifies some informal activities with negligible entry barriers, a notable cost of entry is associated to most activities. The authors find very heterogeneous patterns of capital returns in informal MSE's. At very low levels of capital, marginal returns are extremely high- often exceeding 70 percent per month. Above a capital stock of 150 international dollars, marginal returns are found to be relatively low at around 4 to 7 percent monthly. The authors provide some evidence that the high returns at low capital stocks reflect high risks. At the same time, most MSE's appear to be severely capital constrained.

Abstract

March 2000 - Policies to foster accumulation of the assets needed for agricultural production (including draft animals and implements) and to provide complementary public goods (education, credit, and good agricultural extension services) could greatly help reduce poverty and improve productivity in Zambia. Deininger and Olinto use a large panel data set from Zambia to examine factors that could explain the relatively lackluster performance of the country's agricultural sector after liberalization. Zambia's liberalization significantly opened the economy but failed to alter the structure of production or help realize efficiency gains. They reach two main conclusions. First, not owning productive assets (in Zambia, draft animals and implements) limits improvements in agricultural productivity and household welfare. Owning oxen increases income directly, allows farmers to till their fields efficiently when rain is delayed, increases the area cultivated, and improves access to credit and fertilizer markets. Second, the authors reject the hypothesis that the application of fertilizer is unprofitable because of high input prices. Rather, fertilizer use appears to have declined because of constraints on supplies, which government intervention exacerbated instead of alleviating. (Extending the use of fertilizer to the many producers not currently using it would be profitable, but increasing the amount applied by the few producers who now have access to it would not be.) Policies to foster accumulation of the assets needed for agricultural production (including draft animals and implements) and to provide complementary public goods (education, credit, and good agricultural extension services) could greatly help reduce poverty and improve productivity. This paper - a product of Rural Development, Development Research Group - is part of a larger effort in the group to analyze determinants of rural growth and market participation.

Abstract

Why should countries buy expensive catastrophe insurance? Abstracting from risk aversion or hedging motives, this paper shows that catastrophe insurance may have a catalytic role on external finance. Such effect is particularly strong in those middle-income countries that face financial constraints when hit by a shock or in its anticipation. Insurance makes defaults less appealing, relaxes countries' borrowing constraint, increases their creditworthiness, and enhances their access to capital markets. Catastrophe lending facilities providing "cheap" reconstruction funds in the aftermath of a natural disaster weaken but do not eliminate the demand for insurance.

Abstract

Jim Yong Kim, President of the World Bank Group, discusses the two goals that shape the mission of the World Bank Group: ending extreme poverty by 2030 and boosting shared prosperity. He speaks the need to accelerate a kind of economic growth that's more inclusive, socially sustainable, and protects the environment. He talks about climate change. The frequency, intensity, and duration of extreme climatic events will increase. Droughts, earthquakes, and typhoons will only become worse in the future. He appreciates Japan's focus on doing things before a disaster strikes, as it saves lives and money. He talks about working to refocus developing countries on prevention and preparedness when it comes to disaster risk management. He commends Japan that has been supportive of the World Bank Group's efforts to make innovative financing mechanisms available to governments of developing countries. He appreciates Japan's contribution towards Ebola crisis. He concludes by saying that the Japan's accumulated wisdom has shown the world that taking the proper precautions can save thousands of lives as well as billions of dollars in lost economic growth.
