The paper describes a simple, generic and yet highly accurate Efficient Importance Sampling (EIS) Monte Carlo (MC) procedure for the evaluation of high-dimensional numerical integrals. EIS is based upon a sequence of auxiliary weighted regressions which actually are linear under appropriate conditions. It can be used to evaluate likelihood functions and byproducts thereof, such as ML estimators...

This study examines the relationship between teleworking, gender roles and happiness of couples using data from the British Household Panel Survey (BHPS) and the Understanding Society Survey (USS) during the period 1991-2012. Various approaches are followed, including Probit-adapted fixed effects, multinomial Logit and Instrumental variables (IV). The results support that both men and women who...

In this study we assess the ability of the Marine Recreational Fishery Statistics Survey (MRFSS) to support single-species recreation demand models. We use the 2000 MRFSS southeast intercept data combined with the economic add-on. We determine that the MRFSS data will support only a few species-specific recreation demand models. Considering species of management interest in the southeast, we fo...

In this paper, we develop improved techniques for defending against adversarial examples at scale. First, we implement the state of the art version of adversarial training at unprecedented scale on ImageNet and investigate whether it remains effective in this setting—an important open scientific question (Athalye et al., 2018). Next, we introduce enhanced defenses using a technique we call logi...

This paper analyzes the determinants of life satisfaction in a pooled data set of representative individual survey data from seven East European countries collected during the early phase of economic and political transformation using ordered logit models. Those core sociodemographic and economic variables known to be relevant from studies on the US and West European countries (u-shaped age eff...

This paper studies the saving behavior of rural households in Vietnam from two aspects: volume of savings and methods of saving. Two econometric models are conducted, the first one is a panel data model, used to examine the determinants of household saving; and the second one is a multinomial logit model used to investigate how a household chooses the way to save. Both models are based on the l...

This paper analyzes self-employment dynamics in West Germany over the time period 1984-2004. Using dynamic multinomial logit panel data models with random effects we are able to analyze the mobility between selfemployment, wage employment and non-employment. This allows us to draw conclusions about state dependence and cross-mobility patterns. The results indicate strong true state dependence i...

F several of the largest supermarket product categories, such as carbonated soft drinks, canned soups, ready-to-eat cereals, and cookies, consumers regularly purchase assortments of products. Within the category, consumers often purchase multiple products and multiple units of each alternative selected on a given trip. This multiple discreteness violates the single-unit purchase assumption of m...

Although businesses are increasing their mobile advertising budgets, its strategic value and effectiveness have not been investigated in depth. Using data from an automobile advertisement campaign, we focus on investigating the efficacy of mobile advertising in terms of consumers’ response to sign up for a car test drive in relation to their search behavior. We propose and estimate an empirical...

This paper investigates the role of women’s residential district in the process of family formation in western Germany during the 1980s and 1990s. Our analysis of the transition to first marriage and motherhood is based on the German Socio-Economic Panel (GSOEP), which we merge with a rich set of district-level data. The estimated multilevel discrete-time logit models suggest that (1) basically...
