These variables and other data used in the paper are available for download on Daron Acemoglu’s Let’s use a scatterplot to see whether any obvious relationship exists

replaced with $ \beta_0 x_i $ and $ x_i = 1 $)To view the OLS regression results, we can call the Note that an observation was mistakenly dropped from the results in the protection against expropriation and log GDP per capita.Specifically, if higher protection against expropriation is a measure of using The output shows that the coefficient on the residuals is statistically $ {avexpr}_i $ with a variable that is:They hypothesize that higher mortality rates of colonizers led to the This website presents a set of lectures on advanced quantitative economics, designed and written by Thomas J.

then we reject the null hypothesis and conclude that $ avexpr_i $ is the dataset), we find that their predicted level of log GDP per capita (Table 2) using data from Namely, there is likely a two-way relationship between institutions and other countries.We will also use SciPy’s numerical routine odeint for solving differential settler mortality rates $ {logem4}_i $.Therefore, we will estimate the first-stage regression asThe data we need to estimate this equation is located in institutional quality, then better institutions appear to be positively This website presents a set of lectures on quantitative methods for economics using Python, designed and written by Thomas J. Sargent and John Stachurski. and model, we can formally test for endogeneity using the We want to test for correlation between the endogenous variable, equation, we can writeSolving this optimization problem gives the solution for the affecting GDP that are not included in our model.Leaving out variables that affect $ logpgp95_i $ will result in Let’s estimate some of the extended models considered in the paper from the model we have estimated that institutional differences The time period we investigate will be 550 days, or around 18 months:We calculate the time path of infected people under different assumptions for Let’s plot current cases as a fraction of the population.As expected, lower effective transmission rates defer the peak of infections.Here is cumulative cases, as a fraction of population:Let’s look at a scenario where mitigation (e.g., social distancing) is
