This article discusses the aggregation problem and its implications for ecological economics. The aggregation problem consists of a simple dilemma: when adding heterogeneous phenomena together, the observer must choose the unit of analysis. The dilemma is that this choice affects the resulting...

Econometric studies for global heating have typically used regional or global temperature averages to study its long memory properties. One typical explanation behind the long memory properties of temperature averages is cross-sectional aggregation. Nonetheless, formal analysis regarding the...

The analysis of future energy systems with increasing shares of renewable energy production poses various challenges to models used in the field of energy system analysis. Aggregation is one solution to reduce the computation time of large optimization problems, especially for optimization...

Proper measurement and aggregation of trade costs is of paramount importance for sound academic and policy analysis of the determinants - particularly those of policy - of economic outcomes. The international trade profession has witnessed significant new developments, both on the theoretical...

The Philippines, just like many other developing countries, has measured poverty using one-dimensional monetary-based indicators, although poverty is multidimensional in nature. Various work on generating a multidimensional poverty index (MPI) has been undertaken using data from several...

We estimate a model that allows for dynamic and interdependent responses of morbidity in different local areas to economic conditions at the local and national level, with statistical selection of optimal local area. We apply this approach to quarterly British data on chronic health conditions...

The purpose of this paper is to explore the problem of non-convex labor supply decision in an economy where households feature consumption habits. We show how lotteries as in Rogerson (1988) can again be used to convexify consumption sets, and aggregate over individual preferences. The presence...

We compare direct forecasts of HICP and HICP excluding energy and food in the euro area and five member countries to aggregated forecasts of their main components from large Bayesian VARs with a shared set of predictors. We focus on conditional point and density forecasts, in line with...

This paper shows how to decompose weakly stationary time series into the sum, across time scales, of uncorrelated components associated with different degrees of persistence. In particular, we provide an Extended Wold Decomposition based on an isometric scaling operator that makes averages of...

The current Energy Market is not yet ready for the integration of the Smart Grid context. Concepts such as Demand Response and Distributed Generation, namely renewable energy resources, are not yet included in current business models in order to the system flow properly. Therefore, the authors...

Boards hire and fire CEOs based on imperfect information. Using comprehensive data on 28 cohorts in Sweden, we analyze the role of a potentially important unobserved attribute - CEO health - in corporate governance. We find CEOs are significantly healthier than the population and other highskill...

This note explores the problem of family labor supply decision in an economy with two-member households, joint home production, and fixed cost of joint labor supply. Even though the labor supply decisions are not indivisible per se, the presence of such fixed cost and partners with unequal labor...

There has been much interest recently in the relationship between economic conditions and mortality, with some studies showing that mortality is pro-cyclical whereas others find the opposite. Some suggest that the aggregation level of analysis (e.g. individual vs. regional) matters. We use both...

In this paper, we show that a concept of aggregation can hold in network games. Breaking up large networks into smaller pieces, which can be replaced by representative players, leads to a coarse-grained description of strategic interactions. This method of summarizing complex strategic...

The study of economic growth is central to macroeconomics. More than anything else, macroeconomists are concerned with finding policies that encourage growth. And by ‘growth’, they mean the growth of real GDP. This measure has become so central to macroeconomics that few economists question...

For previously identified weakly separable blockings of goods and assets, we construct aggregates using four superlative index numbers, the Fisher, Sato-Vartia, Törnqvist and Walsh, two non-superlative indexes, the Laspeyres and Paasche and the atheoretical simple summation. We conduct several...

In this article we propose a new methodology for computing the aggregate productivity of an industry, its variations and decompositions of the latter into changes of individual productivities (within effect) and changes in industry composition (between effect). Current aggregate measures rely on...

Various fields of economic analysis (e.g., growth and productivity) and economic policy (e.g., monetary and social policy) rely on accurate measures of price change. Unfortunately, the price index formulae that most price statisticians consider as particularly accurate - the superlative indices...

We present several fast algorithms for computing the distribution of a sum of spatially dependent, discrete random variables to aggregate catastrophe risk. The algorithms are based on direct and hierarchical copula trees. Computing speed comes from the fact that loss aggregation at branching...

We introduce a Divisia monetary aggregate for the euro area that accounts for the heterogeneity across member countries both, in terms of interest rates and the decomposition of monetary assets. In most of the euro area countries, the difference between the growth rates of the country-specific...

Modern regulatory capital standards, such as the Solvency II standard formula, employ a correlation based approach for risk aggregation. The so-called "square-root formula" uses correlation parameters between, for example, market risk, non-life insurance risk and default risk to determine the...

We compile data for 186 countries (1919 - 2016) and apply different aggregation methods to create new democracy indices. We observe that most of the available aggregation techniques produce indices that are often too favorable for autocratic regimes and too unfavorable for democratic regimes....

Numerous theoretical studies have shown that information aggregation through voting is fragile. We consider a model of information aggregation with vote-contingent payoffs and generically characterize voting behavior in large committees. We use this characterization to identify the set of...

In this paper, we attempt to support the argument regarding the endogeneity of productivity to effective demand. Unlike most of the works on the topic, we focus on the role that both public investment and public consumption have on productivity. We suggest, at the theoretical level, that public...

The paper investigates how including the distribution of wealth changes the demand effects of redistributing functional income. It develops a model with an endogenous wealth distribution and shows that the endogenous rise in wealth inequality resulting from a redistribution towards profits...

This Ph.D. thesis focuses on the demand-side management in electricity markets and a new player in the market { an aggregator of exible demand. The thesis consists of three independent chapters investigating the entrance of this new player in the power markets from di erent angles: focusing on...
