3 Sifat dan Karakter Biaya
Biaya Ekspisit Biaya Akuntansi Biaya Ekonomis Biaya Implisit Biaya Alternatif atau Biaya Opportunitas Biaya Relevan Biaya Inkremental Biaya Tenggelam (Sunk Costs) Prepared by Robert F. Brooker, Ph.D. Copyright ©2004 by South-Western, a division of Thomson Learning. All rights reserved. Slide 3

4 Fungsi Biaya Jangka Pendek
Biaya Total (Total Cost) = TC = f(Q) Biaya Tetap Total (Total Fixed Cost) = TFC Biaya Variabel Total (Total Variable Cost) = TVC = f(Q) TC = TFC + TVC

5 Fungsi Biaya Jangka Pendek
Biaya Total Rata-Rata (Average Total Cost) = ATC = TC/Q Biaya Tetap Rata-Rata (Average Fixed Cost) = AFC = TFC/Q Biaya Variabel Rata-Rata (Average Variable Cost) = AVC = TVC/Q ATC = AFC + AVC Biaya Marjinal (Marginal Cost) = TC/Q = TVC/Q

6 Fungsi Biaya Jangka Pendek

7 Fungsi Biaya Jangka Pendek

8 Fungsi Biaya Jangka Pendek
Biaya Variabel Rata-Rata AVC = TVC/Q = w/APL Biaya Marjinal TC/Q = TVC/Q = w/MPL

9 Kurva Biaya Jangka Panjang
Total Biaya Jangka Panjang (Long-Run Total Cost) = LTC = f(Q) Biaya Rata-Rata Jangka Panjang (Long-Run Average Cost) = LAC = LTC/Q Biaya Marjinal Jangka Panjang (Long-Run Marginal Cost) = LMC = LTC/Q

10 Penurunan Kurva Biaya Jangka Panjang

11 Hubungan Antara Kurva Jangka Panjang dengan Kurva Jangka Pendek

12 Ukuran Pabrik dan Skala Ekonomis
Kemungkinan Bentuk Kurva Biaya Jangka Panjang

13 Kurva Pembelajaran Biaya Rata-Rata dari Unit Q = C = aQb
Bentuk Estimasi: log C = log a + b Log Q

14 Meminimumkan Biaya Secara Internasional
Foreign Sourcing of Inputs New International Economies of Scale Immigration of Skilled Labor Brain Drain

15 Manajemen Logistik atau Penawaran Berantai ?
Merges and integrates functions Purchasing Transportation Warehousing Distribution Customer Services Source of competitive advantage

16 Manajemen Logistik atau Penawaran Berantai ?
Reasons for the growth of logistics Advances in computer technology Decreased cost of logistical problem solving Growth of just-in-time inventory management Increased need to monitor and manage input and output flows Globalization of production and distribution Increased complexity of input and output flows

17 Analisis Biaya-Volume-Laba
Penerimaan Total (Total Revenue) = TR = (P)(Q) Biaya Total (Total Cost) = TC = TFC + (AVC)(Q) Volume Breakeven (Breakeven Volume) TR = TC (P)(Q) = TFC + (AVC)(Q) QBE = TFC/(P - AVC)

18 Analisis Biaya-Volume-Laba
P = 10 TFC = 200 AVC = 5 QBE = 40

19 Ungkitan Operasi (Operating Leverage)
Ungkitan Operasi (Operating Leverage) = TFC/TVC Derajat Ungkitan Operasi (Degree of Operating Leverage) = DOL

20 Ungkitan Operasi TC’ has a higher DOL than TC and therefore a higher QBE

21 Estimasi Empiris : Data Collection Issues
Opportunity Costs Must be Extracted from Accounting Cost Data Costs Must be Apportioned Among Products Costs Must be Matched to Output Over Time Costs Must be Corrected for Inflation

22 Bentuk Fungsional untuk Fungsi Biaya Jangka Pendek
Estimasi Empiris Bentuk Fungsional untuk Fungsi Biaya Jangka Pendek Bentuk Teoritis Pendekatan Linear

23 Estimasi Empiris Bentuk Teoritis Pendekatan Linear

24 Estimasi Empiris Kurva Biaya Jangka Panjang
Analisis Regresi Seksi Silang (Cross-Section Regression Analysis) Metode Rekayasa (Engineering Method) Teknik Survival (Survival Technique)

25 LAC Aktual Vs LAC Estimasi Empiris
