We develop and estimate an empirical collective model with endogenous marriage formation, participation, and family labor supply. Intra-household transfers arise endogenously as the transfers that clear the marriage market. The intra-household allocation can be recovered from observations on marriage decisions. Introducing the marriage market in the collective model allows us to independently estimate transfers from labor supplies and from marriage decisions. We estimate a semiparametric version of our model using 1980, 1990, and 2000 US Census data. Estimates of the model using marriage data are much more consistent with the theoretical predictions than estimates derived from labor supply.

The authors propose an Markov Chain Monte Carlo (MCMC) method for estimating a class of linear sum assignment problems (LSAP; the discrete case of the optimal transport problems). Prominent examples include multi-item auctions and mergers in industrial organizations. This contribution is to decompose the joint likelihood of the allocation and prices by exploiting the primal and dual linear programming formulation of the underlying LSAP. Our decomposition, coupled with the data augmentation technique, leads to an MCMC sampler without a repeated model-solving phase.

The aim of this education briefing is to comment upon how basic hedonic pricing models for the valuation of property can be expanded and developed. In this case, the briefing illustrates the use of the new economic approach to the analysis of housing markets, namely the search-and-matching models.

This education briefing discusses the connection of two important economic theories: the hedonic price theory and the search-and-matching theory.

This education briefing gives an example of a (non-linear) form of the hedonic price function.

In cases of mass appraisals, hedonic pricing models can provide a broad indication of value across submarkets and this education briefing demonstrates a theoretical model that can be used to provide a theoretical groundwork for the use of a concave hedonic price function in empirical estimates.

This education briefing shows how basic hedonic pricing models can be enhanced by a search-and-matching approach to determine property values.

This study aims to explore the impact of decentralized long-term rental apartments on the value of in-community housing from two perspectives of housing price and rent.

This study uses the hedonic model to identify the factors affecting the housing value, and the influence of distributed long-rented apartments on the housing value in the community is analyzed from two aspects of housing price and rent by using the ordinary least square method and propensity score matching method.

The primary finding indicates that decentralized long-term rental apartments increase housing prices while decreasing general rental housing rents in the community, with the average degree of increase ranging from 0.93% to 2.59% and the average degree of decrease ranging from 2.23% to 4.34%. According to additional research, the prices of houses within communities rise by 0.042% for every 1% increase in the share of decentralized long-term rentals, while the rents for other types of rental property fall by 0.162%.

The government can regulate the housing market by regulating the access and layout of distributed long-rent apartments.

The findings of this study indicate that the existence and share of distributed long-rent apartments have a heterogeneous impact on the housing price and rent in the community, respectively.

The purpose of this paper is to analyze whether China's exports can effectively improve the global competitiveness of other BRICS countries' exports from the perspective of intra-BRICS export trade.

This paper extends the multinational trade model and analyzes the mechanism of the technological upgrading effect from the perspective of dynamic general equilibrium theory. In addition, this paper uses the export panel data of 217 products with three-digit SITC codes from China to other BRICS member countries from 2000 to 2016 and constructs a dynamic empirical model for parameter estimation.

The results show that China's exports to other BRICS member countries can effectively promote the technological improvement of other BRICS member countries' export products. In particular, the formal establishment of the BRICS organization in 2010 has significantly improved the efficiency of China's export technology optimization.

In the background of the prevalence of anti-globalization and the proliferation of protectionism, this paper proves that the deepening of trade cooperation between other BRICS members with China can help optimize their own international trade competitiveness and allow China's development dividend to benefit more countries and people.

The purpose of this paper is to give a comprehensive solution method for the manipulation of parts with complex geometries arriving in bulk into a robotic assembly cell. As bin-picking applications are still not reliable in intricate workcells, first, the problem is transformed to a semi-structured pick-and-place application, then by collecting and organizing the required process planning steps, a methodology is formed to achieve reliable factory applications even in crowded assembly cell environments.

The process planning steps are separated into offline precomputation and online planning. The offline phase focuses on preparing the operation and reducing the online computational burdens. During the online phase, the parts laying in a semi-structured arrangement are first recognized and localized based on their stable equilibrium using two-dimensional vision. Then, the picking sequence and corresponding collision-free robot trajectories are planned and optimized.

The proposed method was evaluated in a geometrically complex experimental workcell, where it ensured precise, collision-free operation. Moreover, the applied planning processes could significantly reduce the execution time compared to heuristic approaches.

The methodology can be further generalized by considering multiple part types and grasping modes. Additionally, the automation of grasp planning and the enhancement of part localization, sequence planning and path smoothing with more advanced solutions are further research directions.

The paper proposes a novel methodology that combines geometrical computations, image processing and combinatorial optimization, adapted to the requirements of flexible pick-and-place applications. The methodology covers each required planning step to reach reliable and more efficient operation.

The purpose of this paper is to theoretically and empirically investigate the relative effects of wage subsidies and further vocational training on employment prospects.

The paper adopts a theoretical approach that discusses the effects of two major active labor market programs; empirical test using a large administrative data set from Germany and statistical matching techniques.

Previously subsidized individuals and trained individuals who found a job immediately afterwards have the same employment rates.

Firms value training on a subsidized job as much as formal training programs.

The paper presents a model that draws attention to the role of hiring decisions of firms and to the formation of human capital by training programs and by training on subsidized jobs; estimation of relative average treatment effects on the differentially treated, i.e. participants of two active labor market programs; and comparisons not only of all unemployed but also of unemployed persons taking‐up or keeping a job after program end.

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

This paper analyzes labor market responses to productivity shocks when firms set employment criteria on the basis of the likelihood of hiring high or low productivity workers. In response to a positive productivity shock, firms do not raise the criterion as much as the shock, increasing the proportion of low productivity workers among the employed. The observed average productivity may respond negligibly even if employment changes substantially. Interest rate fluctuations can yield an opposite relation between productivity and employment, explaining the weak empirical relationship.
