Welche Rolle spielen nichtstaatliche Akteure, sogenannte »Proxys«, in staatlichen Cyberkonflikten? Und wie unterscheidet sich regimetypenspezifisch das (De-)Eskalationsmanagement? Kerstin Zettl-Schabath vergleicht mithilfe eines umfassenden Datensatzes für die Jahre 2000-2019 die staatlichen...

This paper studies institutional investors' decision-making using novel data from a major proxy advisor. We highlight the significant role of customized proxy advice in shaping shareholders' voting decisions. About 80% of funds receive customized advice, and custom recommendations differ...

Despite the growing need for surrogate decision-making for older adults, little is known about how surrogates make decisions and whether advance directives would change decision-making. We conducted a nationally representative experimental survey that cross-randomized cognitive impairment,...

Suicides hurt families and the US economy with an annual cost of $69 billion. However, little is known about what determined suicide rates in the past. This is likely due to the lack of consistent data prior to the 20th century. In this article, I propose using newspaper suicide mentions for the...

This paper studies measuring various average effects of X on Y in general structural systems with unobserved confounders U, a potential instrument Z, and a proxy W for U. We do not require X or Z to be exogenous given the covariates or W to be a perfect one-to-one mapping of U. We study the...

This paper studies measuring various average effects of X on Y in general structural systems with unobserved confounders U, a potential instrument Z, and a proxy W for U. We do not require X or Z to be exogenous given the covariates or W to be a perfect one‐to‐one mapping of U. We study the...

Research has suggested that night-time light (NTL) can be used as a proxy for a number of variables, including urbanization, density, and economic growth. But, just how close is the relationship between NTL and economic activity? This paper uses a combination of correlation analysis and...

This paper considers techniques for measuring the prevalence of income poverty within small areas, or "neighbourhoods", in Britain. The ultimate purpose is applying such statistics to investigating how the micro-spatial distribution of poverty within cities and regions changes over time as a...

This article presents two new signcryption schemes. The first one is based on Schnorr digital signature algorithm and the second one is using Proxy Signature scheme introduced by Mambo. Schnorr Signcryption has been implemented in a program and here are provided the steps of the algorithm, the...

This paper studies measuring the average effects of X on Y in a structural system with random coefficients and confounding. We do not require (conditionally) exogenous regressors or instruments. Using proxies W for the confounders U, we ask how do the average direct effects of U on Y compare in...

We resolve redundancies in the characterizations of the Banzhaf value suggested by Haller (1994, Int J Game Theory 23, 261-281) and Malawski (2002, Int J Game Theory 31:47-67). In particular, we show that the collusion properties employed by them are equivalent. Combined with the dummy player...

In economics, common factors are often assumed to underlie the co-movements of a set of macroeconomic variables. For this reason, many authors have used estimated factors in the construction of prediction models. In this paper, we begin by surveying the extant literature on diffusion indexes. We...

Diffusion index models have received considerable attention from both theoreticians and empirical econometricians in recent years. One reason for this is that datasets with many variables are increasingly becoming available and being utilized for economic modelling, and another is that common...

Central banks regularly monitor select financial and macroeconomic variables in order to obtain early indication of the impact of monetary policies. This practice is discussed on the Federal Reserve Bank of New York website, for example, where one particular set of macroeconomic indicators is...

Economists are relying on agronomic concepts to construct weather or climate independent variables and improve the reliability and efficiency of econometric models of climate change impact on U.S. agriculture. The use of cumulative heat measures in agronomy (growing degree-days), has recently...

The method of indirect least squares (ILS) using a proxy for a discrete instrument is shown to identify a weighted average of local treatment effects. The weights are nonnegative if and only if the proxy is intensity preserving for the instrument. A similar result holds for instrumental...

The small sample size of contingent valuation (CV) surveys conducted in patients may have limited the use of the single-bounded (SB) dichotomous choice format which is recommended in environmental economics. In this paper, we explore two ways to increase the statistical efficiency of the SB...

We provide new, concise characterizations of the Banzhaf value on a fixed player set employing just the standard dummy player property and one of the collusion properties suggested by Haller (Int J Game Theory 23:261–281, <CitationRef CitationID="CR8">1994</CitationRef>) and Malawski (Int J Game Theory 31:47–67, <CitationRef CitationID="CR11">2002</CitationRef>).

Writing a custom web server with SAPI support is a useful task which helps students and future system architects to understand the link between network programming, object oriented programming, enterprise application designing patterns and development best practices because it offers a vision...

While Canada's economic record over the past decade or so is enviable, GDP per capita remains distinctly below US levels, reflecting a sizeable productivity gap. Among the impediments to faster growth are the taxation of capital and restrictive regulations in certain sectors. Canada's experience...

We analyze a contest between two groups where group members have differing valuations for the contested rent. Generically the pivotal group member with the median valuation of the rent will not act himself but will want to send a group member that has preferences different to her own into the...
