Case & Fair, present a very precise and simplified microeconomic model first, before introducing all the Principios de microeconomía by Karl E Case(Book).
Using a multicountry econometric model, microecobomia examines several important questions, including what causes inflation, how monetary authorities behave and what are their stabilization limits, how large is the wealth effect on aggregate consumption, whether European monetary policy has been too restrictive, and how large are the stabilization costs to Europe of adopting the euro.

Upper Saddle River, NJ. Using a multicountry econometric model, he examines several important questions, including what causes inflation, how monetary authorities behave and what are their stabilization limits, how large is the wealth effect on aggregate consumption, whether European monetary policy has been too restrictive, and how large are the stabilization costs to Europe of adopting the euro.
He finds, among other things, little evidence for the rational expectations hypothesis and for the so-called non-accelerating inflation rate of unemployment NAIRU hypothesis. Principles of economics Case, Karl E. The field cannot advance without the discipline of testing how well the models approximate the data.

To determine the probability that consumers are willing to increase the consumption of vegetables the formulation of a Logit model such as the one used by McFadden was carried out and it is called discrete choice model.
It considers that when individuals are going to make a decision, they are faced with two alternatives of whether to do it or not Madala ; however, the choice depends on identifiable characteristics of the object or good in question.
The model assumes a distribution with a logistic curve where the explained variable or dependent variable Y1 is related, and this is the probability of increasing the vegetable consumption explained through the independent variables Xi using a distribution function Gujarati The probability model would be defined as follows Equation 2. With this exercise we expect that the variables that can explain an increase in vegetable consumption or the elements that would make a consumer refuse to increase it or modify the behavior regarding vegetable download for the family, can be defined.
The decision to use a Logit model and not another type of model as a linear one is because it deals with involving qualitative variables expressed as proportions that show the desires or attitude that the consumer reveals.
The variables that comprise the model can be seen in Table 2. Source: Elaborated by the authors in Once the dependent and independent variables were defined and the parameters were estimated, it was possible to formulate a regression equation to explain the probability of increasing the consumption of vegetables through explanatory variables, which is presented in the following way Equation 4.
It is worth noting that there will be as many pameters as independent variables. According to this equation the probability of explaining the willingness of consumers to increase the consumption of vegetables can be explained by variables such as price, age of the person responsible for downloads in the house- hold, number of family members, family income and schooling level.
The assumptions that were used to formulate the model that was intended to explain the fac- tors that determine the probability of increasing the consumption of vegetables by the families surveyed were: 1 there is a direct relationship between level of income and increase in consumption; 2 there is an inverse relationship between prices and willingness to increase downloadd quantities of vegetables; 3 the number of family members can have a positive effect on an increase in the consumption of vegetables; and 4 the higher the level of schooling, the greater the knowledge of the attributes that vegetables have, and therefore, the probability of increasing consumption is higher.
Statistical significance tests were performed to define the probability of accepting the hypothesis that the p-values are below the significance level in this case at 10 percent , the probability of rejecting the null hypothesis that the parameter value is zero.
Results The data obtained in the field and organized in flat files allowed to feed the Logit model that was formulated, estimating the parameters through the maximum likelihood method. Parameter estimation results and significance tests are presented on Table 3.
Price as an explanatory variable of the probability of increasing the consumption of vegetables was Consumer age as an explanatory variable with a value estimated in The variable number of family members NFM with a positive value of 0.
The variable income with a positive value of 0. Finally, the variable schooling, also with a positive value of 0. Moreover, when the marginal effects were calculated, also this variable showed the highest contribution when explaining an increase in consumption. Discussion The results of the model estimations with all the esteemed parameters and the indicators of the statistical significance tests show the robustness of the model.
This can be seen in the information in Table 3. The values of the statistical Z are higher compared to those of the probability distribution, and this is why the null hypothesis is rejected, considering that the coefficients are equal to zero under a confidence level of 90 percent. This was evident in all cases except for the variable income that was not significant at this level of confidence the sign was as expected , presenting a direct relationship between an increase in income and an increase in probability to aug- ment the consumption of vegetables by families in the Caribbean Region of Colombia.
It should be noted that in most cases these parameters were significant at less than 10 percent, and for this reason, the hypothesis that p is different from zero is accepted.

When considering that the aim of this study was to determine the reasons that could exp- lain the increase in vegetable consumption by families or consumers in the Caribbean Region of Colombia, a large number of variables were taken into account; these included prices, income, family composition, social class, all of which were included in the survey form.
Once the data was cleaned and analyzed and the model was run, only those that showed consistency and gathered general statistical characteristics were price, consumer age, number of family members, income and schooling level.
However, we must clarify that the variables considered in our study were many more than the ones mentioned above. On the other hand, once the parameters were estimated the signs were obtained as expected according to the assumptions of the model.
For example, the direct relationship between the level of income and an increase in consumption were demonstrated by estimating a value of 0.
The inverse relationship between prices and the willingness to increase the downloadd quantities of vegetables could be evidenced given the value of the parameter, i. Equally it happened with the variable schooling that is the one that explains in major proportion the probability of increasing the con- sumption of vegetables. When the marginal effects of the explanatory variables were calculated, with the exception of income, we observed that vegetable prices are inversely related to the possibility of increasing the consumption of vegetables; however, the contributions of each variable are low when explaining the increases in consumption, and the only variable that explains the highest increase in consumption is schooling.
The results obtained show the variable level of schooling as the one that best explains the willingness to increase the consumption of vegetables by consumers in the region. From this result we can infer that when the level of schooling is higher, the consumers will know more about the nutritional properties of the vegetables and this will increase their value. This same result was found in the work of Lacaze who showed that there is a direct relationship between the level of information that consumers have about the product and the ability to identify and assess the benefits of the product under integrated pest management; this in turn has a direct relationship with the quality of the product, in this case, potato for human consumption.
It is also considered that the results of this work have a very close relationship with those found in the case of milk in Argentina, where although consumers are aware of the importance of the quality of the products, the willingness to pay an additional price is very low; this is however increased with the information they have of the quality of the products and give certain priorities when making downloads. In this same sense, the study of vegetables in the Caribbean Region shows limitations in the increase in consumption due to high prices and this can be seen in the negative sign of the coefficient indicating that there is an inverse relationship between prices and the willingness to increase consumption of vegetables.
Similarly, case like that evidenced in this article with the application of the contingent valuation method. Likewise, factors as prices and income as quantitative variables, and qualitative variables as the level of education show that consumers reveal preferences that will allow carrying out prospective analyses of this agricultural line in the Caribbean region of Colombia.
The analysis of the relationship between income and consumption shows the reality of the economic theory in the case of fresh vegetables in the Caribbean Region of Colombia, where direct relationships were found between the increase in income and consumption with a positive sign coefficient, and between prices and willingness to increase consumption with a negative sign coefficient.

Among the variables that establish the possi- bilities of increasing consumption, the one that contributed most to the model was the level of education. This situation is explained by the fact that those who have more information about the features and properties of the good they will consume, in this case, fresh vegetables, may have more reasons to decide to increase their consumption.

In addition to the previous determinants, they included age, gender, and customs, which generates changes in the decisions of the consumer against the download of goods.
The values of the statistical Z are higher compared to those of the probability distribution, and this is why the null hypothesis is rejected, considering that the coefficients are equal to zero under a confidence level of 90 percent.
