Despite a rich literature studying the impact of inequality on policy outcomes, there has been limited effort to bring these insights into the debates about comparative support for government responses to the COVID-19 pandemic. We fill in this gap by analyzing rich survey data from six countries...

In the presence of (at least locally) increasing returns to scale tech- nologies, the paper asks the question: does there exist an economic system which implements Pareto efficient allocations and respects the voluntary participation principle? To answer this question, the paper formulates an...

We examine the connection between discrete-time models of financial markets and the celebrated Black--Scholes--Merton (BSM) continuous-time model in which ''markets are complete." Suppose that (a) the probability law of a sequence of discrete-time models converges to the law of the BSM model and...

This paper studies how wealth and health inequalities have interacted with the Covid-19 epidemic in a way that has reinforced inequalities in income, savings, epidemic risk and even individual preventive behaviors. We present in more detail two papers and their theoretical and empirical results....

This paper examines how contextual and institutional factors are associated with individual subjective well-being, which is measured by individuals' happiness, during the early stage of the COVID-19 pandemic. Using data collected in the People's Republic of China (PRC), the Republic of Korea,...

We consider decision problems under complete ignorance and extend the minimax regret principle to situations where, after taking an action, the decision maker does not necessarily learn the state of the world. For example, if the decision maker only learns what the outcome is, then all she knows...

There is hardly any study on learning inequalities during the COVID-19 pandemic in a low-income, multi-country context. Analyzing 34 longitudinal household and phone survey rounds from Burkina Faso, Ethiopia, Malawi, Mali, Nigeria, Tanzania, and Uganda, we find that while countries exhibit...

This essay attempts to build a simple theoretical model of optimization to decipher the effect of digitalization of a part of the entire production structure which we call here trading or transaction or marketing. In the basic model we use traditional Cobb - Douglas production function to argue...

I suggest that simple enforcement and lobbying models may explain how a small minority of dedicated believers (religious fundamentalists, animal rights activists, woke activists, etc.) are able to impose changes in behavior on the majority in a society who do not believe. With this, a society...
