Regional allocation of investment as a hierarchical optimization problem [PDF]
, 1981 A new formulation is given for the well-known problem of investment allocation between regions in the framework of a planning model. The case of a dual economy with a Cobb-Douglas production function is worked out in detail with an illustrative numerical

Joint Estimation and Bandwidth Selection in Partially Parametric Models
Journal of Applied Econometrics, EarlyView.ABSTRACT We propose a single‐step approach to estimating a model with both a known nonlinear parametric component and an unknown nonparametric component. We study the large sample behavior of a simultaneous optimization routine that estimates both the parameter vector of the parametric component and the bandwidth vector used to smooth the unknown ...

A Consistent Heteroskedasticity‐Robust LM‐Type Specification Test for Semiparametric Models
Journal of Applied Econometrics, EarlyView.ABSTRACT This article develops a heteroskedasticity‐robust Lagrange Multiplier‐type specification test for semiparametric regression models. The test is able to detect a wide class of deviations from the null hypothesis. The test statistic is based on the estimates from the restricted semiparametric model, can be computed in a regression‐based way, and

Using flexible regression models for calculating hospital’s production functions
BMC Health Services Research, 2020 Background The relative lack of flexibility of parametric models has led to the development of nonparametric regression techniques based on the family of generalized additive models. However, despite the potential advantages of using Generalized Additive

Staying Offline or Going Online? Managing the Establishment of Service Platforms
Managerial and Decision Economics, EarlyView.ABSTRACT We study a global game in which consumers and sellers decide whether to join a service platform and interact more efficiently online. Uncertainties about the platform's technology value and users' participation behavior on both market sides cause a coordination problem.

The Impact of Credit and Training on Farmers Efficiency: A Semi‐Parametric Meta‐Frontier Analysis
Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT Smallholder farmers in developing countries face several constraints, which affect their productivity. To reduce these constraints and enhance productivity, government and non‐governmental agencies implement programmes that provide credit and training to farmers.
