In example 10.4, we saw that our estimates of the individual lag coefficients in a distrib- uted lag model were very imprecise. one way to alleviate the multicollinearity problem is to assume that the dj follow a relatively simple pattern. for concreteness, consider a model with four lags: yt 5a0 1d0zt 1d1zt21 1d2zt22 1d3zt23 1d4zt24 1ut. now, let us assume that the dj follow a quadratic in the lag, j: dj 5g0 1g1j1g2j2, for parameters g0, g1, and g2. this is an example of a polynomial distributed lag (pdl) model. (i) plug the formula for each dj into the distributed lag model and write the model in terms of the parameters gh, for h 5 0,1,2. (ii) explain the regression you would run to estimate the gh. (iii) the polynomial distributed lag model is a restricted version of the general model. how many restrictions are imposed

In allentown, pennsylvania, in the summer of 2014, the average price of a gallon of gasoline was $3.68long dasha 22-cent increase from the year before. many consumers were upset by the increase. one was quoted in a local newspaper as saying, "it's crazy. the government should step in." source: sam kennedy, "valley feeling pain at the pump," (allentown, pa) morning call, june 21, 2014. suppose the government had stepped in and imposed a price ceiling equal to old price of $3.46 per gallon. a. using the line drawing tool, draw and label the price ceiling. carefully follow the instructions above, and only draw the required object.

Trecek corporation incurs research and development costs of $625,000 in 2017, 30 percent of which relate to development activities subsequent to ias 38 criteria having been met that indicate an intangible asset has been created. the newly developed product is brought to market in january 2018 and is expected to generate sales revenue for 10 years. assume that a u. s.–based company is issuing securities to foreign investors who require financial statements prepared in accordance with ifrs. thus, adjustments to convert from u. s. gaap to ifrs must be made. ignore income taxes. required: (a) prepare journal entries for research and development costs for the years ending december 31, 2017, and december 31, 2018, under (1) u. s. gaap and (2) ifrs. (c) prepare the entry(ies) that trecek would make on the december 31, 2017, and december 31, 2018, conversion worksheets to convert u. s. gaap balances to ifrs.
