Answer:

La elección del método depende de la estrategia de recopilación de datos, el tipo de variable, la precisión necesaria, el punto de recopilación y la formación del encuestador.

Los principales métodos de recopilación de datos son:

Registros: los registros y licencias son particularmente valiosos para los censos completos, pero se limitan a variables que cambian lentamente, como el número de embarcaciones pesqueras y sus características.

Cuestionarios: formularios que los encuestados devuelven cumplimentados. Un método poco costoso que resulta útil cuando los índices de alfabetización son altos y los encuestados colaboran.

Entrevistas: formularios que se cumplimentan a lo largo de una entrevista con el encuestado. Más caros que los cuestionarios, pero mejores para preguntas más complejas, y cuando se dan unos índices de alfabetización bajos o se encuentra menos colaboración.

Observaciones directas: la realización de mediciones directas es el método más preciso para todas las variables, como las capturas, pero a menudo resulta caro. Muchos métodos, como los programas de observación, se limitan a la pesca industrial.

Presentación de informes: la principal alternativa a la realización de mediciones directas consiste en pedir a los pescadores y a terceros que presenten informes de sus actividades. La preparación de informes presupone la alfabetización y requiere espíritu de colaboración, pero ello puede reforzarse mediante una obligación legal y mediciones directas.

Answer:

The choice of method depends on the data collection strategy, the type of variable, the required precision, the point of collection and the training of the interviewer.

The main data collection methods are:

Records: Records and licenses are particularly valuable for full censuses, but are limited to slowly changing variables, such as the number of fishing vessels and their characteristics.

Questionnaires: forms that respondents return completed. An inexpensive method that is useful when literacy rates are high and respondents collaborate.

Interviews: forms that are completed during an interview with the respondent. More expensive than questionnaires, but better for more complex questions, and low literacy rates or less collaboration.

Direct Observations: Direct measurements are the most accurate method for all variables, such as catches, but it is often expensive. Many methods, such as observation programs, are limited to industrial fishing.

Reporting: the main alternative to direct measurements is to ask fishers and third parties to report their activities. Reporting presupposes literacy and requires a spirit of collaboration, but this can be reinforced by legal obligation and direct measurements.

alexira [117]

Answer:

1. Easing

2. A higher

Explanation:

An adverse inflation shock when modeled is the upward shift of the Short run aggregate supply curve, this brings about higher inflation and causes a lowering of output.

The self-correcting mechanism of the economy will cause inflation to decrease gradually until the economy is back in long-run equilibrium at the original level of inflation.

If there is an intervention with monetary easing, aggregate demand will shift forward and a long-run equilibrium will be established where inflation remains at the higher level.
