Im Zuge des Zensus 2022 werden grundlegende Daten über die Bevölkerung und die Wohnungssituation in Deutschland erhoben. Die Haushaltebefragung auf Stichprobenbasis ist Teil des Zensus 2022, sie wird mit vergleichbarer Methodik wie beim Zensus 2011 durchgeführt. Um das Erhebungsverfahren und...

The Autoregressive Conditionally Heteroscedastic (ARCH) model is useful for handling volatilities in economical time series phenomena that ARIMA models are unable to handle. The ARCH model has been adopted in many applications that contain time series data such as financial market prices,...

Im Rahmen eines einjährigen Entwicklungsprozesses wurde das Fragebogenmodul "Einstellungen zu sozialer Ungleichheit" unter der Leitung der Infrastruktureinrichtung SOEP entwickelt und in der 38. Welle der Haupterhebung des Sozio-oekonomischen Panels erstmalig erhoben. Das finale Fragebogenmodul...

The efficiency of financial markets and their potential to produce bubbles are central topics in academic and professional debates. Yet, little is known about the contribution of financial professionals to price efficiency. We run 116 experimental markets with 412 professionals and 502 students....

In this paper we study the behavior of rivals when there is a known probability of imminent entry. Experimental markets are used to collect data on pre- and post-entry production when there is an announced time of possible entry; some markets experience entry and other do not. In all pre-entry...

We characterize optimal reward-based crowdfunding where production is contingent on an aggregate funding threshold. Crowdfunding adapts project-implementation to demand (market-testing) and its multiple prices enhance rent-extraction via pivotality, even for large crowds, indeed arbitrarily...

This paper investigates the optimal design of crowdfunding where crowdfunders are potential consumers with standard motivations and entrepreneurs are profit maximizing agents. We characterize the typical crowdfunding mechanism where the entrepreneur commits to produce only if aggregate funding...

Im Rahmen der IAB-Erhebung des Gesamtwirtschaftlichen Stellenangebots (EGS) werden Betriebe gefragt, ob sie im Jahr der Befragung die Personalsuche für offene Stellen abbrechen mussten, weil keine geeigneten Bewerber zu finden waren. Unklar bleibt bisher jedoch, ob dieser Suchabbruch das...

While much research has emphasized improving current new product concept techniques, little work has focused on trait-based approaches that specify which consumers are the "right" ones to use in the new product development process, particularly in the consumer goods industry. We propose that the...

This paper investigates the size properties of a two-stage test in the linear instrumental variables model when in the first stage a Hausman (1978) specification test is used as a pretest of exogeneity of a regressor. In the second stage, a simple hypothesis about a component of the structural...

In the linear instrumental variables model, we characterize fixed alternatives against which the test of overidentifying restrictions (OR) is inconsistent. When there is the notion of a “true parameter”, we relate this inconsistency result to the literature on optimality properties of...

In practice, bootstrap tests must use a finite number of bootstrap samples. This means that the outcome of the test will depend on the sequence of random numbers used to generate the bootstrap samples, and it necessarily results in some loss of power. We examine the extent of this power loss and...
