We introduce a long-memory dynamic Tobit model, defining it as a censored version of a fractionally-integrated Gaussian ARMA model, which may include seasonal components and/or additional regression variables. Parameter estimation for such a model using standard techniques is typically infeasible, since the model is not Markovian, cannot be expressed in a finite-dimensional state-space form, an...

DEA is a statistical procedure used to evaluate the relative efficiency of separable entities, termed “decision-making units” (DMUs), where each DMU converts certain inputs into outputs. The methodology can provides an ordinal ranking compared Pareto-efficient frontier, and widely measure require that weights be explicitly set, which more advantageous than conventional measures efficiency. Tobi...

To understand whether telecommuting could be part of the policy solutions for greenhouse gas reduction in the transportation sector, this study uses Instrumental Variable Tobit models and data from 2001 and 2009 National Household Travel Surveys to explore whether telecommuting reduces or increases the daily work and non-work vehicle miles traveled. Our findings suggest telecommuters have more ...

Parties in pluralist democracies face numerous political issues that citizens may be split on, but most models of party competition assume a simple, often one-dimensional structure. We develop a new, inherently multidimensional model of party strategy in which parties compete by emphasizing policy issues. Issue emphasis is determined by two distinct goals: mobilizing the party’s core voters and...

Abstract In this paper we provide an overview of the patterns of intergenerational proximity and coresidence of adult children and their mothers in the U.S., using data from the National Survey of Families and Households (NSFH) and the U.S. Census. We highlight the importance of three specification and sample choices in the analysis. First, most previous studies consider coresidence to be the l...

For a long time, China's economic development ignore the constraints of resources and environmental costs but onesided pursue GDP. In 2014, the State Council issued a document to develop the Yangtze River economic zone into a "green ecological corridor". The green development of the Yangtze River economic zone is of high-profile. This paper attempts to consider the resource and environmental fa...

A large amount of studies on online review has been conducted, most of which are based on studying English-speaking reviewers. However, it is unclear whether customers who speak other languages, such as Finnish, German and Japanese, would exhibit similar preference in defining the helpfulness of online review or not? There is a lack of knowledge on how different cultural backgrounds affect user...

The aim of this paper is to test the determinants of Research Joint Ventures’ (RJVs) group dynamics. We look at entry, exit and turbulence in RJVs that have been set up under the US National Cooperative Research Act, which allows for certain antitrust exemptions in order to stimulate firms to cooperate in R&D. Accounting for unobserved project characteristics and controlling for inter-RJV inter...

The medical care system in China has experienced significant changes during three decades of reform, and thus result in a need to investigate the effects of medical reform. This paper investigates the technical efficiency of Chinese hospitals in 31 provinces during the period from 2002 to 2013 by proposing a new global generalized directional distance function (GGDDF) approach taking account of...

Major DAC donors are widely criticized for weak targeting of aid, selfish aid motives and insufficient coordination. The emergence of an increasing number of new donors may further complicate the coordination of international aid efforts. On the other hand, new donors (many of which were aid recipients until recently) may have competitive advantages in allocating aid according to need and merit...
