Well, first of all, not having the second World War is redundant. The second World War was caused by the way that the first World War ended. Some other ways the world could have been different
The Russian Revolution might not have happened. If Russia's armies had been free in 1917, they might have put down the rebellion before it really started. If the rebels had even tried.
The Great Depression might not have happened. One of the triggers was Germany ceasing to pay its war reparations from World War I.
No Holocaust. Hitler was a reaction to the Great Depression and the loss of World War I.
No Cold War. Without communist Russia and World War II, what starts the Cold War?
No communist revolution in China. The communist party in China was founded in reaction to events in Russia.
Of course, it also could have been pretty much the same. The assassination of Ferdinand was the trigger for the war, not the cause. All the same pressures would have been there and the war might just have happened later, with a different triggering event.
If you want more of an answer, you might consider posting more about the assumptions of your change. Did the assassination attempt happen but fail? Was it caught before it started? What happened? Note that even an unsuccessful attempt might have triggered World War I.
Also, consider limiting your time period more. Note that some of my changes are dependent on previous changes. If you select different assumptions, then they are no longer valid. For example, the Russian Revolution might have happened in 1922 if World War I started in 1919 as the result of a different trigger. And then we'd get back the rest of the changes that were dependent on no World War I as well.
You also may want to consider limiting the question geographically. For example, without World War I, what would have happened to the government in Russia? Would the Tsar have stayed in power? Would there have been a military coup? Would the Bolsheviks have ended up in power anyway? There are a number of possibilities here and which one you choose will influence what happens later.
If you want to know what the world of 2016 would be like without the assassination of Ferdinand in 1914, you need to figure out what the world would be like in 1919 (end of war in our world), 1929 (start of the Great Depression), 1939 (start of World War II), 1952 (Eisenhower elected), 1959 (Cuban Revolution), 1991 (dissolution of the Soviet Union), etc. Many of those events would not have occurred without World War I--perhaps none. At each step, there are a number of possibilities that depend on previous choices. What choices do you make initially?
