In many cases, aggregate data is used to make inferences about individual level behavior. If there are social interactions in which one person’s actions influence his neighbor’s incentives or information, then these inferences are inappropriate. The presence of positive social interactions, or strategic complementarities, implies the existence of a social multiplier where aggregate relationship...

Existing statistical ultimate (Frisbee) analyses rely on data aggregates to produce numeric statistics, such as completion percentage and scoring rate, that assess strengths and weaknesses of individuals and teams. We leverage sequential, location-based data to develop completion and scoring maps. These are visual tools that describe the aggregate statistics as a function of location. From thes...

We study the demand function of a group of S members facing a global budget constraint. Any vector belonging to the budget set can be consumed within the group, with no restriction on the form of individual preferences, the nature of individual consumptions or the form of the decision process beyond efficiency. Moreover, only the group aggregate behavior, summarized by its demand function, is o...

The goal of our project was to predict the average spread of a loan given its other features and analyze which features have greater effects on its riskiness. In addition, given aggregate data on the number of defaults by property type, we examined whether those property types with higher default rates also had higher average spreads. The hope is that we will be able to predict the riskiness an...

Using aggregate data from the Annual Survey of Industries, we analyze profitability in India’s organized manufacturing sector from 1982-83 to 2012-13. Over the whole period of analysis, the rate of profit grew at about 1 percent per annum, primarily driven by a rising share of profits. We use structural break tests to identify medium and short run regimes. We find two medium run regimes, one of...

A macroeconomic examination of unemployment obscures much of the rich detail that underpins the labour market. Nevertheless, it enables us to analyse the broad trends that have occurred over the past twenty years on both the demand and supply sides of the labour market. In the next section we examine these trends at an aggregate level. The aggregate unemployment rate has risen as a result of a ...

Recent pioneer papers of Sen (1981, 1985, 1992) have emphasized that poverty is a multidimensional issue. Hence, it should be seen in relation to the lack of important "basic needs" or "basic capabilities." This recommendation has motivated many researchers to focus on the way multidimensional aspect of poverty should be measured and aggregated. This survey synthesizes the contribution of the m...

The theory of belief revision and merging has recently been applied to judgement aggregation. In this paper I argue that judgements are best aggregated by merging the evidence on which they are based, rather than by directly merging the judgements themselves. This leads to a threestep strategy for judgement aggregation. First, merge the evidence bases of the various agents using some method of ...

This paper presents an analysis of the liquidity effect in the euro area – the link between the availability of aggregate liquidity and the interbank overnight rate. Applying a set of assumptions which also lead to the “martingale property” of the overnight rate, a model linking the latter to the expected aggregate liquidity conditions is formulated and calibrated. Different assumptions for how...
