Summary: This paper focuses on estimating the efficiency of the medical laboratories industry. Three stochastic frontier models are employed, and the results show that the US medical laboratory industry has high technical efficiency. Furthermore, there is a positive correlation between efficiency and market valuation.

Summary: This study models the relationship between within-establishment union membership rate and wage inequality in Norway. The findings suggest a negative relationship between union membership and wage inequality, which becomes stronger with a more permanent shift in union membership. Additionally, union membership plays a larger explanatory role in the lower part of the wage distribution compared to the upper part. The impact of union density on wage inequality is conditional on the presence of a collective agreement.

Summary: The study examines the impact of executive equity incentive on enterprise innovation and digital transformation and explores the differences between state-owned enterprises and private enterprises. The results show that executive equity incentive has a positive effect on enterprise digital transformation and innovation.

Summary: This paper proposes testing asset pricing models using multihorizon returns (MHRs) and applies it to prominent linear factor models. The study finds that these models typically fail to accurately price longer-horizon returns, with pricing errors similar to the risk premiums they were designed to explain. The errors are traced back to conditional factor dynamics. Incorporating factor timing into the models often exacerbates pricing errors, posing a challenge for future research.

Summary: The study examines a set of potentially misspecified structural models, combines their likelihood functions geometrically, and estimates parameters using composite methods. In Monte Carlo simulations, composite estimators outperform likelihood-based estimators in mean squared error, and composite models are superior to individual models in the Kullback-Leibler sense. The study also discusses Bayesian quasi-posterior computations, comparing the approach to Bayesian model averaging, finite mixture, and robust control procedures.

Summary: This study addresses the identification issues of counterfactuals in dynamic discrete choice models, introduces a general framework for investigating a broad class of counterfactuals, and provides examples through numerical analysis of a firm entry/exit problem and an empirical model of agricultural land use. Identified and nonidentified counterfactuals of interest are illustrated in each case.

Summary: This paper proposes a two-step estimator of a nonparametric regression function using Kernel regularized least squares (KRLS) with a parametric error covariance. The approach improves KRLS by incorporating a parametric error covariance, allowing for heteroskedasticity and autocorrelation in the estimation of the regression function. The estimator is obtained through a two-step procedure, where the parametric error covariance is estimated using KRLS residuals in the first step and a transformed model using the error covariance is estimated by KRLS in the second step. Theoretical results on bias, variance, and asymptotics are derived, and simulation results demonstrate the superior performance of the proposed estimator compared to KRLS in cases of heteroskedastic and autocorrelated errors. An empirical example involving the estimation of an airline cost function under a random effects model with heteroskedastic and correlated errors is provided, including the evaluation of derivatives and determination of average partial effects of the inputs.

Summary: Adverse selection not only leads to the crowding out of socially beneficial trades, but may also result in more bad trades occurring simultaneously. Due to information asymmetry, these bad trades frequently happen in insurance, credit, and used-car markets.

Summary: This paper introduces a dynamic spatiotemporal autoregressive conditional heteroscedasticity (ARCH) process to describe the effects of time, space, and spatiotemporal factors on the volatility of an outcome variable. A generalized method of moments (GMM) estimator is derived based on linear and quadratic moment conditions, with consistency and asymptotic normality demonstrated. The model's performance is studied through simulations and applied to analyze monthly log-returns of condominium prices in Berlin from 1995 to 2015, revealing significant volatility spillovers.

Summary: This study evaluates the flavonoid and aroma composition of wines treated with shade films. The results show that shade films positively impact the color, phenolic index, and total anthocyanins of grapes, as well as improve the aroma profile of wines. These findings are important for combating warmer growing conditions associated with climate change.

Summary: This paper examines the identification and estimation of installed-base effects for product adoption using group-level panel data, and proposes a modified BLP approach to address endogenous sample attrition and homophily issues. The proposed method incorporates changes in group composition and uses lagged variables as instruments to handle sample attrition and homophily. Monte Carlo results are presented to illustrate identification challenges and the effectiveness of the proposed estimation method.

Summary: This study applied the new sprayed engineered cementitious composites (NS-ECC) to the initial support structure of the Wulingtou tunnel in Xuancheng City and compared its performance with ordinary sprayed concrete (SC-C25). The results showed that NS-ECC exhibited improved mechanical properties and energy storage characteristics under different water-containing states and loading rates.

Summary: This paper investigates the impact of intermunicipal cooperation on firm creation in France during the 2000s. The study finds that a higher participation of municipalities in cooperation positively influences the establishment of new firms. Additionally, the research shows that business tax sharing plays a crucial role in favoring firm creation. These findings align with the theories of fiscal federalism and suggest that the goals set by the 1999 law were effective in boosting firm creation.

Summary: Studies on public municipal employment are lacking, despite the fact that municipalities are major employers in many countries. To address this, researchers constructed an original panel dataset of 8421 municipalities in France from 2002 to 2008, and found that cooperation leads to downsizing of municipal personnel. Additionally, they identified a causal impact of employment at the inter-municipal community level on municipal employment, which is positive for less experienced municipalities but negative for more experienced ones, indicating a time lag in the substitution process between the two levels. Moreover, cooperation prompts mayors to increase municipal employment, especially in high-employment communities.
