For the macroeconomics under the model of uncertainty and expectation, we have expected productivity which depends on the signal and probability of different productivity. Example like s = {good, bad} and z = {zl, zh} with prob(good, zh)=0.8 prob(good, zl)= 0.2 prob(bad, zh)=0.4 prob(bad,zl)=0.6

and our expected productivity is ze(zh)=0.8*zh+0.2zl or ze(zl)=0.4*zh+0.6zl and both option zh or zl has a fixed cost from government G

I want to ask, under the same model, if the productivity fixed prob doesn't change but the government spending varies(G) could I applied the same process to calculate expected government spending?
