The magnitude of an economic base multiplier depends upon the amount of money that "leaks" out through expenditures outside of the city limits. the economic multiplier tends to be higher with each of the following except the larger the city is. the less isolated the city is from other cities. the more tourism a city brings in. a higher percentage of local household income is respent within the city.

The best answer to the question: The economic multiplier tends to be higher with each of the following except:___, would be: The less isolated the city is from other cities.

Explanation:

The economic base is defined as the set of economic activities that a city, or region, offers to those outside of that area, and which encourage the entrance of new income sources to the city, region, or area. These activities include local industries and employment opportunities, among other things that encourage people to stay within that city´s limits and spend their income there. As such, from the list of options in the question, the one factor that could not be counted in to multiply the economic base would be for a city to be too close to others, because in this case, people would have options to seek for other opportunities outside of the city; which would defeat the purpose of economic base and the growth of the city. This is why the option above is the one that needs to be excepted.
