We propose the group knockoff filter, a method for false discovery rate control in a linear regression setting where the features are grouped, and we would like to select a set of relevant groups which have a nonzero effect on the response. By considering the set of true and false discoveries at the group level, this method gains power relative to sparse regression methods. We also apply our me...

In this paper we consider the classical problem of dividing a land among many agents so that everybody is satisfied with the parcel she receives. In the literature, it is usually assumed that all the agents are endowed with cardinally comparable, additive, and monotone utility functions. In many economic and political situations violations of these assumptions may arise. We show how a family of...

The impact of redistributive policies on voluntary contributions is still not well understood. While a higher level of redistributive taxation decreases the price of voluntary giving, it also changes the income distribution by decreasing income inequality. This paper provides a controlled laboratory experiment to investigate the net impact of the tax rate on public goods provision. The experime...

We consider a three-level distribution network involving a raw material supplier with imperfect quality, a manufacturer and several retailers. A production-inventory model accompanied by a partial backlogging approach is developed by considering random disruptions. Any batch received from the supplier is inspected by the manufacturer and if any flaw is visited, all the goods in the inspected ba...

In the distribution of goods from a central depot to geographically dispersed customers happens quite frequently that some customers, called linehauls, receive goods from that depot while others, named backhauls, send goods to it. This situation is described and studied by the vehicle routing problem with backhauls. In this paper we present a new tabu search algorithm that starting from pseudo-...

Bergstrom showed that a necessary condition for a Pareto optimum with non-paternalistic altruism is classification as a selfish Pareto optimum. This paper shows that Bergstrom’s result does not generalize to the benefit-cost analysis of generic changes in public goods. There may exist good projects that will be rejected by a selfish-benefit cost test, a selfish test error. Selfish test error is...

This work is based on a study of capital goods suppliers to the power generation and distribution, materials handling, and offshore industries. Business processes are project-based and interdependent. They include sales, marketing, tendering, engineering, manufacturing, procurement, assembly, and commissioning. A model is presented which groups these processes into three categories: nonphysical...

We describe an exchange market consisting of many agents with stochastic preferences for two goods. When individuals are indifferent between goods, statistical mechanics predicts that goods and wealth will have steady state gamma distributions. Simulation studies show that gamma distributions arise for a broader class of preference distributions. We demonstrate this mathematically in the limit ...

This paper presents estimates of the impact of exchange rate movements on the industry-level price of investment goods using a panel of OECD countries. An exchange rate depreciation (appreciation) causes a significant rise (fall) in the prices of the investment goods used by most industries, but the magnitude of this effect differs greatly across sectors. A currency depreciation causes a strong...
