l. Specify a model of enlistment where recruit quality depends on supply and demand. What shifts the supply curve? What shifts the demand curve? Demonstrate how the model explains the effects ofthe unemployment rate, advertising, demographic shifts, pay, surges in patriotism, increased casualty rates and other variables you think are relevant on the number and quality of recruits. Step 1:Specify the model Goal: Specify a model of enlistment where recruit quality depends on supply and demand. Concrete thought:Starting from the military demand and supply function, a new model and function are formed by taking the military demand and supply function as independent variables and the conscription quality as dependent variables Concrete content 1 In the past, the demand for military labor in the market was assumed to be an exogenous variable. However, in Larry De Boer and B. Wade Brorsen's \"The Demand for and Supply of Military Labor," we find that the demand for military labor may be influenced by income and cost factors, such as pay level, military budget, and geopolitical events & conicts. These factors can form the following supply function. Military Demand Function: Qd = D(P, B, G) Qd = Quantity ofmilitary personnel demanded P = Pay level (wages and benefits) for military personnel B = Military budget G = Geopolitical events and conflicts, which includes surges in patriotism and increased casualty rates. Previously, military manpower research mainly focused on the determinants of military labor supply, especially the impact of various forms of military compensation and business cycles on enlistment. This area of research is well-established, and scholars generally believe that military supply is related to pay level and demographic factors. Combining the Phillips curve, we incorporate the impact ofthe unemployment rate into the supply function. as well as the role of advertising observed in everyday life. This leads to the formation of the Mathematically, the equilibrium is represented by: D(P, B, G) = S(P, A, U, D) Then we assume that recruit quality depends on the supply and demand for military personnel. The model will be: RQ = f(Q., Qs) = f(D(P, B, G), S(P, A, U, D))
