| 摘要/Abstract | 本文以樂透公益彩券爲主題，分析台灣民眾的購券行爲。首先，我們以限制應變數模型來估計累積頭彩機率函數，發現台灣民眾選號行爲是屬於自覺性的選擇而非隨機性的選擇，而此將易提高累積頭彩的機率，降低報酬預期價值。其次，我們利用有效價格模型估計彩券的需求函數，實證結果顯示台灣公益彩券無論是隨機性的選號或自覺性的選號，價格需求彈性均遠大於1，代表目前彩券有效價格過高，應降低售價或徵收率才可提高彩券收入。 We analyze the demand for Taiwan's lottery tickets during the first 186 lottery drawings. Using a limited dependent variable model to estimate the rollover probability function, we find the players select numbers consciously, not randomly. This raises the rollover probability of the grand prize and reduces the expected value of return. Moreover, we employ the effective price to estimate the demand for lottery tickets. The result shows the price elasticity is larger than 1, implying the revenue raised from the lottery will be increased by reducing the selling price and the take-out rate. |
