| 中文摘要 | 代表性個人的總體經濟模型所估計的最適專利長度比目前的實際專利長度長很多。而在固定死亡率的假設下,考慮永遠年輕的重疊代模型,延長專利會擴大跨代間的貧富差距,所估計的最適專利長度較短,但仍長於目前實際的專利長度。當我們考慮到死亡率會隨年齡的增加而增加時,可以從專利延期中受益的老年人之死亡率更高,縮短了最適專利的期限。雖然仍然比目前的實際專利要長,但已經非常接近了。 |
| 英文摘要 | Macroeconomic models using representative individuals estimate optimal patent lengths that are much longer than current actual patent length. In the forever young overlapping generation model under the setting of fixed mortality, extending patents expands the inter-generational wealth gap, and the estimated optimal patent length is shorter, but still longer than the current actual patent length. When we consider the phenomenon that mortality increases with age, the mortality rate of older people who benefit from patent extension is higher, resulting in the optimal patent length being shorter. Although it is still longer than the current actual patent, it is already very closer. |
