Learning AJKA is best done by starting with POLAJKA, then FORJAKA, and finally applying WREGAJK program. 

POLAJKAClick figure to expand (Return: click Back in balk)

In POLAJKA you will be using ten economic policy instruments, which have their influence on economic growth, inflation, unemployment and balance of current account. These central goal variables have their target values for two subsequent years. AJKA gives forecasts, 8 figures, which somewhat deviate from the target values. You alter (+ or -) some instrument(s). AJKA calculates the value of the loss function on the basis of the differences between the target values and the AJKA forecasts. The closer to the target values the model is steered, the smaller will be the loss function value. You will soon learn the connections between taxation, government expenditure, incomes policy etc. and the goal variables and will be able to use the appropriate instrument to guide the economy closer and closer to the given target values

FORAJKA requires more understanding than POLAJKA with its automatic feedback via the loss function. But it also gives more. You must know your aims. You needn't, however, create from scratch, because there is always the latest AJKA forecast as a starting point. You can make an infinite number of alternatives to it:
