| This paper argues that mainstream economics does not follow the positivist research tradition it (often implicitly) claims to follow and expresses some serious doubt that econometrics in particular can make economics a hard science. Mathematical rigour and sophisticated statistical techniques may be regarded as persuasive analytical tools in economics, but their mere application does not guarantee good research practice. The paper outlines an alternative methodological view of pragmatic instrumentalism in which the well known tools of economic analysis can find a new place. Instead of relying on a narrow rule that purports to produce universal truth, this view encourages to increase the target area for questioning and probing. Much more attention is paid... |

| Las fuertes inversiones iniciales que son necesarias para comenzar una actividad acuícola, unidas al período tan dilatado del ciclo de explotación y al riesgo que esta actividad comporta, son situaciones que comprometen el futuro de la actividad cuya continuidad pasa necesariamente por la consecución de la viabilidad económica. Por ello, es importante prestar atención a los estudios que justifiquen esta viabilidad económica considerando aspectos tales como la propia flexibilidad operativa o el valor estratégico que tiene cada proyecto de inversión, a menudo considerados factores críticos para la supervivencia. Desde esta perspectiva, se pone de manifiesto la necesidad y la oportunidad de la investigación, basado en la aplicación del método de Opciones... |

| Cross-sectional data sets containing expenditure and quantity information are typically used to calculate quality-adjusted imputed prices. Do sample size and quality adjustment of price statistically alter estimates for own-price elasticities? This paper employs a data set pertaining to three food categories-pork, cheese, and food away from home-with four sample sizes for each food category. Twelve sample sizes were used for both adjusted and unadjusted prices to derive elasticities. No statistical differences were found between own-price elasticities among sample sizes. However, elasticities that were based on adjusted price imputations were significantly different from those that were based on unadjusted prices. |

| Managers of greenhouses, nurseries, and landscape contractors participated in five focus group discussions on labor-related risks. Managers conceptualize labor risks along the human resource management process: (1) recruitment and selection, (2) training and development, (3) performance evaluation and discipline, (4) careers and relationships, and (5) compensation packages. In addition, they identified (6) immigrant employees and (7) labor laws and regulations as sources of risk. They recognized a large number of risk-increasing attributes, but also a number of mediating strategies to reduce these risks. |
