I estimate the effect of team production on labor productivity and product quality using a cross section of British establishments. A distinguishing feature of this study is its use of a structural model that treats as endogenous the organizations’ choices of teams and whether or not to grant...

The Klein-Leffler (1981) model of product quality does not explain why high-quality firms would dissipate the rents they earn from quality- assuring price premia, and it relies on consumers knowing the cost functions of firms. In the present paper, consumers do not know any firm's cost of...

Facing a growing competitive environment, higher education institutions have increased dramatically the competition for recruiting and retaining students providing a high quality service as a solution to compete. Frequently, researchers who have studied the service quality and client...

The Web portals business model has spread rapidly over the last few years. Despite this, there have been very few scholarly findings about which services and characteristics make a Web site a portal and which dimensions determine the customers’ evaluation of the portal’s quality. Taking the...

We propose a new hypothesis testing method for multi-predictor regressions with finite samples, where the dependent variable is regressed on lagged variables that are autoregressive. It is based on the augmented regressiom method (ARM; Amihud and Hurvich (2004)), which produces reduced-bias...

In a presentation to the American Economics Association, McCloskey (1998) argued that "statistical significance is bankrupt" and that economists' time would be "better spent on finding out How Big Is Big". This brief survey is devoted to methods of determining "How Big Is Big". It is concerned...

In this paper we consider the problem of making inference on a structural parameter in instrumental variables regression when the instruments are only weakly correlated with the endogenous explanatory variables. Adopting a local-to-zero assumption as in Staiger and Stock (1994) on the...

Consider the hypothesis H that a defendant is guilty (a patient has condition C), and the evidence E that a majority of h out of n independent jurors (diagnostic tests) have voted for H and a minority of k:=n-h against H. How likely is the majority verdict to be correct? By a formula of...

We propose new data-driven smooth tests for a parametric regression function. The smoothing parameter is selected through a new criterion that favors a large smoothing parameter under the null hypothesis. The resulting test is adaptive rate-optimal and consistent against Pitman local...
